With several eggs hatching and the babies in the brooder outgrowing it and the "dorm" I have set up for teenaged birds not prepared, I moved my feathered teens to the big coop last night. There's 2 coops with a shared run, housing standard chickens, bantams, and muscovies. I nestled them into the bigger of the coops with a heat lamp, food, and water. The big hens were coming in without incident, so I left it as is since the teens didn't seem interested in going into the run. DUMB ME. I just found one of the 6 teens ( a buckeye who I suspect was a roo) laying on the run floor, plucked, and gutted. It was so horiffic I can't go into details. It was just one of the worst things I have ever seen and I've seen a lot. The teens are now safe, their coop door locked. The cannibals can't get them.
