I brought home 3 babies from the farm store and went back for the 4th. I picked out a RIR, Barred Plymouth Rock, White Crested Black Polish, and an Ameracauna. They are beautiful and now 6 to 7 weeks old, and each one has a unique personality. Can't tell if we have all hens, yet. The Ameraucana (Bella) is suspect of being a roo. Any thoughts as to sex?
