Hello We are new to having chickens. I received 25 chicks from McMurray on Monday but we are only keeping 8 there are 7 different breeds of all female chicks. Where we live we cannot have roos. We plan to sell or give away the ones we can't keep. The question is when should I sell them? Should I wait until they are over 8 weeks to make sure there are no roos. Even at 8 weeks will I be able to tell? I think I can finally tell the breeds apart so we can keep one of each kind. I would hate to get rid of the extras and accidentally keep a roo or two. I think McMurry says they are 90% accurate. The coop we are building will only be big enough for 8 mature chickens(4x8 coop and 8x10 run). They are in a big box in the basement right now. I'm not sure we will have room to keep them when they are 8 weeks old. Do you think we should sell now or later? How much room do 8week old chicks need? Will people want to buy 8week old chicks?
