We incubated 12 eggs, 5 hatched... only the BR (2)survived. At 5 weeks, it's become obvious that one is a roo and the other a pullet. How long can they stay together without separating? Is it a given that I'll need more hens ? or is it possible they may live together quite well? We're new to all this but enjoying the experience! Thanks for your input. All of you have already been a wealth of information!
