Crossed Beak Chickens

A Crossed beak (also called a scissor beak, crooked beak or lateral beak deviation) is the term used for when the top part of a bird’s beak does not align properly with the lower portion, resulting in crossed appearance. The severity of the deformity can range greatly from case to case. In this article, I will be giving some further information on the causes of crossed beak deformities. I will also offer tips and advice on care based on my experiences with crossed beak chickens.

Most beak deviations resulting in crossed/crooked beaks begin in embryotic development. Sadly, most chickens hatched with the defect will not live to adulthood. However, this does not mean that chickens hatched with beak deviations can not live happy, healthy, functional lives. The implication of this is that they will require a little more attention than chickens without deformities to be happy and healthy.

What Causes Crossed-Beaks in Chickens?

Fetal miss-positioning during embryotic development:

Usually, a chick has one wing sheltering its head while it is in the egg. If the chick is not positioned this specific way during fetal developement, it is more prone to skull malformation (which may result in a crossed beak).

Nutrient Deficiency: 

Particularly deficiencies of folate (also known as folic acid or vitamin B9), vitamin D, Biotin (also known as vitamin B7), calcium and/or methionine. If chicks are deficient in any of these nutrients, they are far more likely to develop beak deviations during critical growth stages.

Liver Disease:

 With liver disease, chickens are more prone to nail/beak overgrowth, which can lead to beak deformations/deviations. However, liver disease usually only occurs in older birds.

Genetics:

Certain breeds are more prone to lateral beak deformations than some others. Such varieties include Ameraucanas, Crested Varieties (such Polishes as and Crevcouers) and Easter Eggers (which are not an actual breed).

Since crossed beak chickens will need a little more care than the flock member, spotting the early signs of a cross beak is important.

What Crossed-Beak Chickens Need:

A Hand with Hygiene:

As is the case with crossed/scissor beak chickens, their ability to perform cirtain activities (like preening for external parasites) is at a disadvantage. This means that they need a little helping hand. (You can read about various treatment options for external parasites here: Lice & Mite Treatments for Chickens.)

Soft, Healthy Feed:

Chickens with crossed beaks have a difficult time eating the same foods in the same way as other chickens. This results in likely one of the biggest issues for crossed beak chickens: getting enough food. Chicks with beak deformities often can not eat straight, dry chick starter very easily. If this is the case, I advise feeding crossed beak chicks younger than four months, chick starter mixed with a little plain yogurt. Elly, my crossed beak Crevcouer, could eat regular chick starter without additives for the first few months. When she grew a bit, I shifted her over to mainly layer pellets mixed with yogurt or water (about a 1 to 1 ratio). On the side, I feed her some healthy, nutrient dense treats/scraps (like squash, bananas and boiled or scrambled eggs).

Space:

Chickens with crossed or crooked/deviated beaks are often smaller than average and low in the pecking order. To top this, crossed beak chicks may be a little more cumbersome when eating. This means that they’ll need to spend an extra minute or two at the feeder to get enough food. Overcrowding can cause crossed beak chicks to get pushed aside or trampled… This is why I advise keeping crossed beak chicks with small groups  and allowed plenty of space with adequate food/water access.

Beak Trimming:

Chickens’ beaks continue to grow throughout their whole lives very much like human fingernails. Normally, chickens wear down this new growth by pecking, preening and well… just being chickens. Since chickens with crossed beaks do not wear down their beaks as evenly, they usually require trimming. Trimming makes it easier for crossed beak chickens to grab things. It can also prevent injury caused by sharply worn edges. Though the need varies from case to case, I trim Elly’s beak about once every other month. Beak trimming only takes a few minutes but it is delicate business. For beak trimming, I advise using regular sharp, human finger nail clippers or cuticle trimmers or over dog/cat nail clippers. This is because beak trimming requires precision.

  1. Yes i was wondering why chickens get so paralyzed when they are placed upside down… and also how you are so beautiful…please tell me that much.

    1. Hello Don,
      The reason that chickens display paralyzed behavior when placed up-side down is because of an alteration in blood-flow. Basically, it is the same reason why some people get what we call a ‘head-rush’ when they stand up to quickly.
      I hope that this information answered your question and was helpful to you! Thanks for visiting my site.

      1. Thank you for getting back to me so quickly. I didnt know that so im glad you did! I used to put my grandmas chickens upside down on my head to balance them when I was a kid. This is actually your aunt mel and i love you 😉
