The last couple nights when I have closed them up for the night I noticed that one ameraucana hen is missing her feathers on her back and has a yellow hue to the area. I watch all of them closely and I am positive she had them before. It looks like feathers are possibly growing back in but they are just over 2 months old and I believe that she’s too young to molt? Only one in the flock that has this issue. Any help / suggestions are appreciated.
