hello,, a "pecking order" question, if you don't mind? my day-old mixed flock chicks arrived today,, now i'm official! i'm already seeing the 'pecking order' thing, but one (a barred rock) concerns me. there's another BR, and is not doing what this one is doing. she is not only pecking at the eyes of the others but grabbing at their eyes, n i'm afraid of traumatic injury (i have some very rare breeds in there n would hate to have to replace or put down). i separated the one w cardboard partition 8" high, n the doggone thing just found a way to get back over!! (this one's strong!) i can't go higher bc they must share the heat lamp, n that's as high as i can go w the 'wall'... should i b concerned?? does this one need to b culled?? i cant keep it separated. i would appreciate your response and experience. thanks!
