Backstory - we have a flock of neighborhood guineas (4) that roam between 3 lots. We feed and water them and they show up every morning. 1 has been missing for weeks. We assumed it was a predator. Fast forward to today and we found a crying keet in our lot, on her/his own trying to get in with my 6 week old chicks in their outdoor coop. We have older hens and 1 rooster that didn’t pay much attention to it. I caught her/him and placed her in the coop with my chicks. What do I do? It looks to be about 4-5 weeks old and fully feathered. No ear lobes or anything yet. Do I keep it with my chicks? I see no other sign of mother Guinea (I’ve heard they’re awful mothers) or any other keets. It was crying for a very long time with no response. What to do?
