I wonder if this is behavior that will be repeated, or if these chicks were just taking advantage of an unusual opportunity. I have 18 chicks, RIR & SLW, 6-8 weeks old, in a large PVC tractor. This afternoon I came out to find one of the SLW stuck on his side halfway under the bottom of the tractor and many of the other chicks pecking at him. He was in a bare place where they dust bathe, he must have dug down too deep and gotten lodged under the bottom edge of the tractor, and couldn't get loose. I didn't know whether to be disgusted or amazed. Disgusted to find that the chicks had not only pecked the feathers & skin off his back, but they'd pecked a huge hole in his backside so I could see far into his abdominal cavity. But amazed that this chick was still alive, alert, breathing, and not yelping, not making a sound. I was also both grieved & grateful. Grieved that the chicks had helped themselves to a cockerel chick that was going to be my family's dinner, but grateful that they hadn't wasted a more valuable pullet. Do you think they might do this again, or are incidents like this usually done on impulse, motivated by unusual opportunity? How could I keep this from happening again?
