Just picked up the eggs from the post office. I opened the box and they seem well packed. I'm going to use a broody to hatch them. I don't remember where, but I think I read somewhere that I should let the eggs set for a period? of time before putting them under the hen. I need step by step instructions here. I've never done this before and have no clue what comes next. I am also going to put a few of my own eggs under the hen in case the others don't hatch for some reason.
