When do they move out of the brooder and how old are they? I have a bunch of Guinea Keets. I don't know how old they are (I think I bought them in mid-September), but they are starting to get waddles and loose the feathers on their head. At night could drop into the 40s but so far its been 50s and 70+ during the day. I keep the brooder in the house and I turned off the brooder bulb a few days ago with no issues. I am building a coop and pen on Tuesday specifically for my guineas in which I plan to keep a breeding flock. I also plan to have a free range flock from those I don't plan to breed. When do they move out of the brooder and how old are they?
