Judging by my own 2 Silkie hens -- no, they don't fly well but they can get lift for short distances and my 2 girls can hop up as high as 4 feet. They don't do it often but mine are capable of it. When I make barriers across doors in the house, I have to put up something higher than a baby gate because if they're determined they will hop up 4 feet or get injured thinking they can do it. If the barrier is higher it will discourage their hopping attempts.Yep. She's special needs so she'll be living indoors for the foreseeable future.
I've definitely been considering Seramas! My boss has some so I get to work with them daily. I love the little guys! I'm just not sure I want to get something with much flight capability. I'd like to make the brooder about 3' tall but I don't want to cover it so it's very easy to access. But I also don't want chickens running all over my bedroom! Maybe a Silkied or Frizzled Serama? I know both have less flight capability than a flat feather, but I'm not sure if they'd be capable of hopping 3 feet.
Holy crap I love that design! Similar to what I want to do, except I don't think I'm going to cover it so I can access it easily. I was gonna do a partial roof and put the laying box, roosting shelf, and feeders and waterers hung under it. I was just thinking I would do a 2x3 board over the end, to make a little overhang/safe space.
