When should/can I move a hen, hatchling and eggs?

I wouldn't lock the other hens in with the new mommy. I had the same situation as you. I just went out every morning and locked the flap after all the hens left. Giving Mommy hen some down time with the new chicks. By day 4 I took the mommy and chicks and put them in a large dog crate. Letting them out during the day and locking up during the night. Did that for another week and then let my hen back to the rest of the flock and did things normally. Watch out for your cats, one of my cats killed a chick that wasn't staying near mommy hen.

 

I wouldn't leave her with the others. I've moved broodies when I probably shouldn't have- one was nesting in the hen house and the eggs were peeping, moved her and eggs into their own house/ run and they were fine, and hatched fine. The other I moved once her chick had hatched, together with the other eggs. None of the other eggs hatched but she kept sitting on them so I don't think they would have hatched anyway. As long as she's got her chick she'll probably be happy. Good luck!

 

I kept mine a bit separate from the flock for about 2 days. I made a nest in a cardboard box, with a bit of hay and set it under the roost, as that is the only floor space in my coop. I locked my layers out of the coop all night, but they were locked in the run. It was nice here, and they were fine. I went down in the morning let the layers outside to free range, and opened the coop to the run. Then at night when she bedded down, I let the layers in and locked the run. After the second day, I opened the run and left the run open to the layers and the Mama. That night they all slept in the coop

Mine are all together, and once in a while a chick will get a thump from another hen, but mama takes care of it. I do let mine out to free range so there is ample space. But I was gone for two days, and they had to all stay in the run/coop together, and when I got back all was fine. The Mama hen generally keeps herself between the babies and the other hens and rooster. She puffs up big if one of them get too close. and if one of her chicks gets to peeping she comes charging in.

The problem with separating them is the WHOLE reintroduction issue which does not always go well. Mine are all together, and I like it that way.

Also, from day three, mine were out free ranging with Mama, being fed grasshoppers. Today they are 12 days old, and I saw one catch his/her own grasshopper.

I guess what I am really trying to say, is once they are all hatched, and following Mama, I would put them back into the flock. Then you won't have reintroduction issues.

I usually try to move her and the eggs away from the flock within the first few days. We have to fasten her into her "new" nest for a day, so she takes to it and won't abandon it.

If it gets so hot she holds herself up above the eggs, I try putting frozen bottles of water in the nest. If that doesn't work, I put them all into a dog crate and bring them into the air conditioned kitchen so she'll set properly.

Upsetting her always runs the risk of her stepping on and damaging an egg or a chick.
