1 is probably an old English game bantam.
2 Golden Sebright
3 frizzle black Cochin
4 Probably a Millie Fleur D'Uccle, but could be a buff Brahma. A clear picture of the comb would determine which it is. Brahmas have pea combs, D'Uccles have single combs.
5 maybe black tailed buff Japanese bantam
I am not sure on chick 2. Nothing I can think of is an exact match. It has yellow legs, so not an old English game. Other breeds I dismissed are Rhode Island red bantam and Japanese bantam. It could be an Easter egger. If it is not clear in a few weeks, post again.
Those pictures are better. I think she's a female black Minorca. I see no male specific feathering. Minorcas are known for having very large combs and white earlobes. They lay large white eggs.
I think she's a regular barnyard mix, and probably a bantam was one parent. I don't see any obvious signs of pure breeds being involved in her parentage, so maybe both parents were mixed breeds themselves. She's healthy and cute. That's more important than having a pure breed.
Maybe just a hatchery quality partridge rock. The dark chipmunk pattern and eye stripe are not typical.
It could also be something else. I think it is a case of time will tell. Post an update in a few weeks if you can.
Silkie mixed with larger breeds. Someone had to have white earlobes, since he does, so maybe Leghorn or Andalusian. It's impossible to know his exact mix.
I think it is a cockerel, too. If you have other roosters they might be keeping him from crowing and mating. I will be surprised if it turns out to be a pullet because the comb is big, and the hackle feathers seem long.
Both genders should have spikes at the back of their combs. My hunch is that these are both males because females usually have flat combs until they are older. But hopefully I am wrong.
