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.
