My entire flock of chickens are bantams. I got 25 bantams in March 2006 and still have most of those along with " new" ones of course. Some of my bantams are bigger than others and I have 3 golden hens ( can't tell them apart ! ) that have been good layers. I now have 2 small white hens ( about 6 mos. old ) who I think have started laying robin size eggs !!! I think they are Japanese bantams white black markings on the white. Does anyone know if hen size and egg size are directly related ??
