I found my favorite chicken dead today and am wondering if anyone has an ideas on sudden death in chickens. I'm not 100% sure of sex but am thinking it was a rooster. This bird had appeared to me to be the healthiest of the flock. Was the quickest growing, feathered earliest and was definitely the dominant bird in the coop. Raised from a day old with 7 others. The coop is spacious and there is a securely fenced run attached for them to freely come and go. Run area is about 12 x 12 or so. The bird was eating commercial grower ration free choice, water always available and some leftovers from the kitchen. I found her/him on their back up against the coop in the run. No visible signs of fighting, no blood, no wounds. There was a small bald area on the neck which I assumed was moulting. One of my friends' daughters said the bird was acting strange for awhile Friday...it had dug a hole and was twisting itself right around, even its neck looked twisted she said. Anyone have any idea what might have happened and if I should do something different for remaining birds? Thanks.
