quail with chickens

[CliftonQuail]

Even with bantam breeds? I thought they are around the same size

I found this image online that should help a bit:

Chickens are flock animals, would not be happy alone, even with quail. They need flock mates, other chickens.

I want an animal I can bond with unlike skittish quail.

Kinda sounds like quail aren't for you, I would maybe suggest you do away with/rehome your quail or just keep them in their own enclosure. And research other birds/animals that may fit your wants/needs rather than trying to adapt the bird/animal to fit yours. I am sure you have only best intentions for your birds/animals but to be a good bird/animal keeper you have to meet the needs of what you are raising to keep them (Safe and Happy) no matter what our use for them is. As far as diseases chickens are carriers of some that are not harmful to chickens but very deadly to gamebirds.
