My three BO chicks are 7.5 weeks old and getting much to big for their temporary pen. I've moved them outside into the big girls run. And they are spending their first night outside tonight. YEA!!! I'm going to try letting them out with my adult BO and JG tomorrow. They've been looking at each other for a week now so they are used to each other. And I'll set up a "panic room" for the babies to escape from the big hens. And I'll sit with them to see what happens. I don't expect it to go perfect tomorrow. But I'm hopeful if I keep doing this slowly, that I can fully integrate them over the next week or two. They are ready to have full use of the big girls run and I'm ready to get them out there. Wish me luck!
