Ok, I don't mean to sound dumb, I know nothing about hatching eggs, nothing! If I have say 4 chickens that lay, and I want to hatch out eggs, can I only do those 4 that I collect that day? What about If I wanted to sell hatching eggs? Would I need 12 hens laying on the same day? What if I bought hatching eggs that are mailed to me? Will the incubator time change? I'm sorry these questions are kinda dumb, but I really have no clue, and want to learn everything I can. Thanks In Advance!
