I tried that the first year that I tried to breed as many as I could. I had alot of trouble selling them and the feed/space demands made it a hassle to raise them up to that age. Most people didn't want to buy juveniles despite it being the smarter move. Now I just sell my IB and IBBS chicks at 2-3 weeks locally to save on space and maximize profit. The color mutation birds are kept until they can be reliably sexed. I wish people would want to wait until they were older and stronger but many people who are getting into peas treat them like they would buying chickens.Personally I don't sell them until they are at least 3 months old - could be just me but it seems that they are stronger at this age.
