I have three RI Reds that are 2 yrs, and 5 not quite sure that are a year. My new chicks are 5 1/2 weeks so I moved them outside this weekend. The big ones seemed ok at first, then we found one of the babies dead in the yard, pecked to death. I wasn't positive that maybe one of them might have stepped on her and broke her neck, but then the next morning I watched as the big ones were trying to attack a baby. Did I put them together too soon? The big ones all of a sudden have feathers missing and big red spots on their chests. I believe they have started attacking eachother too. Is this normal? I have seperated the babies from the bigger ones again, just to be careful. Any ideas???? I am really ticked that they killed one of my babies.
