First off, I cannot believe how fast these babies are growing! I weighed several of them at 17 days old. They ranged from 4 oz to 6.4 oz. They're huge! They're about 22 days now. I've been raising their light every few days, especially since it's been in the high 70's here. About when should they be ready to wean from the heat? I'd like to move them onto wire, but don't want to do it too soon. They are going to be too big for their horse trough brooder in about, oh, 2 days~LOL
