I have 2 BOs but one died last night. After researching the web, I found that the symptoms matched that of an Egg-bound hen. The only thing is that all of them were laying fine, as well as eating, drinking, walking, etc. I noticed the fluffing of the feathers yesterday and one BO got it the nest instead of the roost last night. I thought she was just laying again, but this morning she was dead in the nest. Now, tonight my other BO was in the nest instead of on the roost. I brought her inside and treated her for egg-binding with a warm bath, a massage and some KY. (Sounds like a good date) I did not feel any egg inside her and I do remember her laying today, but she was still fluffed up with her tail in the air. She is resting now inside in a basket with a heating pad. Any clues? The rest of my flock consists of 4 Sexlinks and 3 Ameraucanas. The diet hs been the same since they were 6-months old, they will make 1 year in Feb. They free range around the yard. Thanks for any help!
