Been reading about moving chicks from the brooder to the coop, and feeling a little concerned on how to do it. Was trying to get a handle on the temperatures that are ok for chicks, but you all know about the Midwest - one night it is 40 degrees, and the next night it is 70! Just like in the daytime, we can have 80 degrees one day, and then 50 degrees the next! How do you get your chicks used to these big swings in temps? I know once they are grown they'll be fine, but I'm just trying to figure out how to help the chicks get through it without getting sick. I do have 22 chicks, so I'm hoping that helps them to snuggle in and keep warm when they will need it. How do you "harden off" your new little chickies in the fall or spring when temps are so unpredictable?
