I haven't had these long enough to know a lot about them. I do know they like to group nest and like to brood. I've seen as many as 6 or more of her birds all piled together in a nest. She'd mark the eggs and pull any layed before or after a time window so they hatch together with not too many eggs at once. Just enough eggs for each bird to have a couple eggs to sit on. She'd pull the babies to brooder raise though.
My friend used to let them all out to play occasionally and they usually focused on foraging and each other. But they could fly well and i remember one of the hens was always going on top of a shed to just look around. They always put themselves to bed well though. They haven't had any free range time here yet because of a hawk that keeps landing in and circling our pine tree. It doesn't seem interested in anything but our tree but I'm sure that'd change fast if i let any birds out! In their coops, they're taking the highest perches and those are shoulder height.
I've got my first eggs under a hen right now (my incubators devoted to call ducks for now) so will get to see for myself how true they breed. She kept them separated by color with orange breasted, chocolate breasted, black breasted and the ones she called lavender. For now I'm keeping them as she had them though I've never bred for anything but pets. Very very curious to see what comes out of the eggs for myself! Send me a message whenever you want to trade!
