New here but not new to raising chicks...grew up on a farm with lots of chickens...I have had a previous flock of hens that were all killed by a mink...after several years I thought I would try again...I have 4...definitely 2 Buff Orpington hens, an Americana, and a Buckeye Brown...not quite sure if the brown is a roo or hen...can anyone help? THANKS!
