I could not, for the life of me, figure out why one of my little cochins was missing her head feathers. I finally saw what has been happening. She is lowest on the pecking order. When she has to lay her egg, she runs and I mean beats feet!! right into the same nest that another hen is in. Then a fight happens. The other hen tries to get her out but the cochin will not go. She tucks in and refuses to get out. The other hens are grabbing and pulling her head feathers trying to get her to vamoose. Do they make chicken helmets? LOL. I don't even know what to do about this situation.
