I bought 10 baby chicks from Tractor Supply about 5 weeks ago, only 2 were pullets. The rest were straight run, so I'm dying to know what I've got!!!! The RIR and ISA Brown were the pullets. They had a bin labeled BSL and I got one from there but after doing some research I'm not so sure that's what it is. Kind of looks like a Barred Rock to me but I'm a newbie so who knows?? Any insight will be most appreciated!!!
