I have 6 (I think Leghorns) that are just about fully feathered out, and about 5-6 weeks old. They have been out of their brooder, and free in the coop for about 3 weeks now. This last weekend we finished their outside run, and I've been opening the door for them to go outside during the day (It's been in the high 70's here) , but they don't want to go out. When the door is open, they hide behind their tub brooder, and don't move around much. Should I just keep the door shut for now, or give them the opportunity to go out if they want? I am shutting them in at night. They are also perching at night now in the coop, but I'm still putting their heat lamp on for them at night. It's getting down into the 40's, and I'm not sure they need it still. Should I turn that off now, or just leave it for them if they want it? Don't want to push them to 'grow up' too fast!
