These chicks are a little over a month old, and theyre already getting different comb sizes. Im used to big chickens like RIR, Rocks, Australorps, etc, so I dont know if this is coincidence or what. Can someone with little banty/japanese experience tell me what you think? These are black japanese..is the one on the lef end a roo? These are the white ones. Same group, different picture. Lastly there are the oddballs. A Black tailed buff, two black tailed whites, and a Mottled. Im really hoping the mottled is a hen. He/she is bigger than the others, but porportion wise, her comb is as big as the ones I think are hens. So, if you can tell by now, and I think I can, then why? Is it because theyre banties? I thought it took a while to tell with them too. Thanks.
