Hello everyone...Currently, I am worrying about my 4 wk old chicks. I know for sure that my SilkiexJG is a roo - he is developing his feathers slower, is /huge/ compared to his fellow hatch mate and his legs are quite thick. However, I'm worried about my RIRs. If they end up as roos, I'd rather find them a home but RIR roos are known for their bad temper - so they'll probably end up as dinner.
