Gotcha, I was thinking in the coop, they have a place to run to should the other chickens go after them. If they're the same size or close to your older chickens, then I like @sourland's idea, just put them together at night.Thank you, we definitely designed the coop with square footage minimums in mind. We can only have 4 birds at a time, so now that 2 have passed, we are replenishing the flock. My main question isnt about whether they will fit, but whether we should leave the in a dog crate either inside or outside the coop at night time? Whenever the time comes for them to roost with the resident hens, we wont have a way to keep them seperated on the roosting bars. Sorry if my initial post was confusing
