it is called cross beak or scissor beak
Scissor beak, aka: crossed beak, crooked beak, is a condition in which the top and bottom beaks do not align properly. It can be caused by genetics, an injury or the inability to maintain the beak’s length and shape by normal honing on rocks or other hard surfaces.
at 6 weeks old. The crooked beak begins to become apparent.
Scissor-beak varies in severity, but most chicks can eat and drink independently. Crossed beak need not be an automatic death sentence as believed by some. Most cross-beaked chicks adapt and thrive, leading long, happy lives. However, there are some chicks in which the defect is too severe for them to eat or drink independently and they can not survive without constant assistance.Since crossed beaked chickens cannot pick up pieces of food using both halves of their beaks as utensils, they adapt by scooping food into the bottom half of their beaks.It helps to put feed in deep dishes.Some chicks find it easier to eat a feed to which water has been added to make it the consistency of oatmeal. Grinding up feed in a coffee grinder and adding water to make a wet mash may help severely scissor-beaked chickens.The important thing to watch out for with this condition is that the chicken is able to eat, not only due to their physical limitations but because other flock members may attempt to keep them away from the feed. If that occurs, the chicken should be put in a safe place where only she can access the feed. Chickens maintain the length and shape of their beaks by wiping them on rocks or other abrasive surfaces while foraging, but scissor beaked chickens have difficulty with this routine task.Cutting her beak will become a regular thing to keep it from growing too long When chicks have scissor beak, it is safe to assume that genetics are to blame, therefore breeding them as adults is not recommended since the condition can be passed down to future generations.
