Yesterday, I noticed a hen acting a little strangely and not moving around as she should. I thought she was just hot and chilling in the shade. I got busy and forgot. I remembered later and looked out the window to notice she wasn't there anymore. Good deal. Nope. We found her dead in the barn. I know it could've been a number of things. Then this a.m. I found another hen dead jn the coop. None of them act sick. None of them look sick. I did notice these 2 withdrawing somewhat from the others and really haven't been eating with the rest. But, we free range, so I wasn't worried they wouldn't get enough to eat. Should I take one to the vet to see if what they had contagious? I'm a little scared about that. This may have been going on for a while. We recently removed a rooster from them since he got into a fight with our other rooster. Would that have affected our hens? Also, we had to take our rooster to the vet for an eye injury (from the rooster fight), could he have unintentionally brought something home? We held him the entire time other than the examining table and scale. I assumed they kept that super clean. I haven't noticed any worms in their poop. No coughing or wheezing sounds. No weak birds.
