Our hens frequently co brood, but not all birds have a cooperative mindset. Best case is if you can put them in floor boxes in the same area, but spaced out a couple feet, with enough space to allow a couple of feeders and waterers. This allows them to see each other and the chicks from early on. Often even if the hens dont completely cobrood this allows them to recognize the other chicks as part of their group, rather than intruders. Then the hens care for anyone's chicks rather than only their own. And the chicks grow up mingling so they have a bigger group of 'friends' to hang with as they grow.
Some hens are clearly and stubbornly solitary, you should be able to see it early... if one is like that then just allow her space to move to the level of privacy she wants.
This our coop. Mind the construction. We added a patio and more fun is coming.
Oh, and you can see the two white bantam Cochin frizzles and the random tiny chicken in the photo.
