Is there a method to letting the girls free range? It's been so long since I've done this I can't remember. I'm thinking tomorrow might be the day but do I just open the door and let them out in the hopes they will come back? I have 19 speckled Sussex and 4 guinea. Should I keep 3 of the guineas in and just let one out for a day or two? They've been cooped for four weeks now; 7 weeks old.
At that age they should come back, at dusk check them and make sure they have gone in, as they maybe sitting outside or under the house/pen. It may take awhile for them to venture out or they might instantly go out but they should come back, especially if you leave them food in the coop/run and only feed them in there for a week or so
I have a run too. I'm a little scared to let them on their own for hours, because there are cats in my neighborhood. I let them tub sound the yard and they really enjoy it. Good luck.
