I have two broodies sitting on fertilized eggs due to hatch on Fri. their nesting boxes are about a foot and a half off the ground with a tray for roosting which I have shavings in, and a ramp to go down to the ground where the water and feed are. There is a 10x10 fenced in run but I do let the hens, I have one that is not sitting, out during the afternoon to roam and get them in before dark. How do I handle the chicks? I think I need to get chick starter. Do I need to isolate from the other hen? I'm new at this, so please ignore my ignorance.
