It depends on how close to the nerve centers the beak is broken. My roo broke his beak in a skirmish with one of my dogs. It is nearly grown back. It was broken back about 1/3 of the way on top. It has been several months but the beak is now 3/4 grown back. all but the tip is regrown. The beak is much like our fingernails.I got a 11 month old silver laced wyadotte roo today and I was observing it and I looked at his beak and the top part at the end was broken i was wondering will it heal and fix or will it stay?
