When they integrate I am opening up the little run so they all have run of almost my entire backyard + hideyholes, don't worry there will be Plenty of fleeing space. This is day 4 of the babies having been visible to the other girls all day, day 5 of them being visible at least at night.
I've unfortunately caught a bug of some sort, but as soon as I'm better I'm gonna grab a second pair of eyes for supervision and try to let everyone get along together.
The biggest threat is openings only big enough for the chicks. If momma can't reach them she can't protect them.
