One of my girls is molting and has lost weight. Then last night she tried to roost on the top of th hutch. All of the girls usually start to roost inside the hutch at dusk and I lock them in for the night. When I picked her up to put inside the hutch, I could tell that she hade lost weight. Is this normal? Should she lose weight and have odd behvior during molt? Your thoughts please... I'm worried!
