So new to raising keeping backyard chicks. My son's show banty started showing up with a missing section of comb and missing feathers. This occurred once our cute feed store spring chicks reached about 3 months old. I noticed the adolescent or teenage rooster started jumping and "attacking" our gorgeous show banty. She must be in her twenties in human years. Now she disappears for days on under our back yard shed. When she reappears she is no longer sweet, mellow, and dignified and "show quality" in behavior. She runs between my son and the shed. She is moody, snooty, and acting like shes got great booty. We are now aware enough to keep our sweet bantys separate from the large chickens. The large chickens I now call evil.. to which my son takes offense. The bantams and large chickens now rotate yard time. I feel like a warden of a low security prison. So is this possible, do large chickens mate with bantums. Are not the "large chickens" a bit young to fertilize. Please feel free to correct my terminology and ideas about chicken mating.. Also, we are concerned she may actually have a nest outside our yard in the green belt or in a neighbors yard. Can we go to Radio Shack and buy a chicken tracker? Any ideas? Lastly, until we figured out what might be going on we kept her caged with her sisters for at least 12 hours. Does this mean the hatching process was killed. She still disappears to where we hope is sitting on her eggs.
