I have a broody SLW. This is the second time she has gone broody, so I've decided to give her a few eggs. We get back from spring break March 19th. I want to time the hatch for when we get back. 21 days right? I know some hatch late, but do some hatch early? If I stick fertilized eggs under her March 8th, that would mean they should hatch the 29th. Is that enough overlap? (eggs go under her March 8th, we leave the 19th and come back the 26th, the eggs hatch the 29th.) Or should I wait longer??????? What would you do? **In case you're worried about a broody mama all alone, I have a live-in house sitter that will take great care of her. I just don't want to miss the hatch! My other question is, should I move her? I have two coops. One is new and in the garage. My chickens are quite unfamiliar with it. She's in the coop right now with all the other three, on the favorite nest of course! I can move the others to the new coop, or move her to the new coop. The problem is both have rather steep ramps. I could close them I suppose. I don't have the type of coop to put a dog crate in to separate them. Should I move the broody and upset her, or move the other three and upset them?
