...but today I came here to get some answers from the experts. We have (as of April 2011) been raising chickens and on August 24th we bought 15 Cornish Broilers chicks. I will do a search but the condition I'm about to describe is to me, unheard of... and I'm older than you probably. The condition was noticed this morning. A lethargic female with dirty wings was kind of cowering in the corner of the pen. It was kind of cool this morning (after a rain last evening) and I just wanted to wash her off a little and maybe get her up and active. Her crop was still full from yesterday so I surmised that maybe she was bound up or something. Not so. I went and got her this afternoon and noticed that her wing bones (both sides) had penetrated the outer skin layer and were dried out and protruding. I have some pictures. We have ruled out predators. Perhaps a overbearing rooster got frisky? i don't know. At this age she weighed 5 1/2 pounds. I did not notice any unusual behavior yesterday. There are about 4 roosters among the other 11, they are all the same breed and age. It was my first chicken kill. We do plan to process the rest in the next week or so but it saddens me that any animal had to go this way. Is this condition known to anyone here? Can a bird grow that fast as to burst from their own skin? If I had to guess I would say that she has just tried to fly too much or that a rooster pecked her skin apart, or both. I'll try to post pictures. My partner wants to know if it could have been some type of bacterial infection that caused rotting? (the thought of that is awful) Both of us were actually relieved when I cut her neck and she bled out. They're fed once per day and 15 birds ate about 3 pounds of food per day. I have decided to fed them smaller amounts but more often until next week arrives.
