I have several chickens and 10 guinea hens. One guinea hen, who I'd thought had been taken by a predator, showed up with 13 keets probably 2-3 days old 9 weeks ago. We captured them and the hen and put them in a very large screened cage about 1/4 mile away from the pen. They are ready to be released now but I'm not sure how to go about it. Shall I just leave the door open and see if they come back at night for their grain? Will they eventually join the mother hen's group with her? Her mate often comes to see her during the day. Any info would be appreciated greatly.
