I just had an 8yr old hen pass away while on the way to the vet
, so that leaves me with another 8yr old and a 3yr old who is currently raising three, 3 week old chicks. (Cream Legbar, so I know they're female). My issue now is that Gabby, my lone older girl is by herself in my main coop, while Lacey and chicks are in the "nursery". (The nursery, 80 sf is in one corner of the main run/coop area, which is 300 sf so they have been "next" to each other a lot.) At what point can I integrate them all together? When she's weaning them? At that point, I'd like to open the nursery door and leave it open for them to wander in the main run area with the 2 adult hens, leaving the nursery door open. Gabby doesn't act interested in the chicks at all, although she's staying near the nursery since losing her best buddy (& while the other was sick). I thought about letting them all integrate now as neither of the adult girls are aggressive, (the one who passed was the number one hen and sometimes aggressive), but I'm not sure if this is a good idea or not. I could really use some advise please!!!
