Hello All, Last night I went out to check on my girls before bed time, and noticed that one of my white leghorns was not up on the roost with the others. I picked her up to place her on the roost, and noticed several of the feathers on her underside near her vent were missing. I just assumed she was starting to molt, and didn't think anything of it. She was also acting a little bit lethargic, but I thought that was due to me waking her up. Then this morning I went back out to check on them, and she was off the roost on the floor. She had passed within an hour or two. Up to this point I believe she was laying regularly, and seemed to be ok otherwise. Any ideas of what caused this death? I also have another white leghorn that is showing similar feather lose on one of its wings, again, similar to a molt. Should I separate her from the flock until it clears up? Thanks in advance!
