Hi, I am new to hatching my own chicks and I don't know if this is the right place to put this but I am getting my incubator soon and I have some un-answered questions about hatching. 1. Do you put the eggs in the incubator right after they have been laid or how long can I leave them? 2. I want to hatch a full incubator, can I stock up the eggs? 3. Can I build my brooder right into my existing coop with my hens? 4. How old can the chicks be when I put them in with my existing flock? 5. And last of all, a dumb question, how do the chicks become male and female? Thanks!
