I have silkies that are almost 3 weeks old. They are the first chickens we've ever had. We have a coop & run out in the backyard, but the brooder is in our basement. I'm wondering when I can put them in outside. I've been bringing them out about once a day for the past week & they seem to love it! I live in Michigan. Right now the daytime temps are about 80 degrees & it's getting down to about 55 degrees at night. Any hints or tips appreciated. Thanks!
