Assistance appreciated Leghorn hen about 6 1/2 months old. Yesterday when let out of the henhouse/coop into the yard she went just outside the door and lay down. Didn't wander the yard with the rest of the chickens. Today she didn't want to move at all. My daughter put her into one of the nest boxes and she hasn't moved. Her comb has become very droopy. Upon close inspection today it appears there is some brown forming on the tips. She does appear to be much thinner than the other 2 leghorns and their combs are "upright/floppy" whereas hers just droops. No other birds have any symptoms. We are treating a RIR with a prolapse, but I would believe that to be unrelated. No sign of injury or trauma I don't know if she has eaten or drank. I just isolated her into a porta-kennel. I gave her an egg scrambled with the shell in case she wants some food. I haven't seen her poop. Hope to see it in the kennel now that she is isolated. She has been laying for about 4-5 weeks. Having read threads, I've sent my wife to the feedstore for wormer and sulmet. Any assistance would be appreciated. These are our children's "pets".
