So I have a batch of cornish x and white leghorns in a brooder together all the same age. I noticed today the cornish x are really starting to stand out. They are now about 4 days old. The cornish are also marked with black dye on their heads. To my surprise one was very tiny and had an empty crop so I fed them and watched him chase the other chicks excitedly but not eat himself. Upon closer inspection this little guys bottom beak is a quarter of the length it should be. He is unable to even eat and must have been living on stored energy. Can I save him by maybe trimming the top beak or should I just put him down?
