2. Probably a Black-tailed White Japanese bantam (or a cross with a Japanese bantam anyway); and a pullet
3. Probably a Spangled OEGB (Old English Game Bantam); definitely OEGB but could be another color Like Mille Fleur although the color looks a little dark; definitely a rooster
4. Looks like a Light Brahma to me; not sure on the sex though although with the comb starting to get pink it could be a roo. Probably a little too early to tell for sure though.
I did think 4 was a light brahma. In other pictures thats what it looks like. I will try to repost one of them. It dosent look like the silkies. I have 3 the same age so I can compare them. The EE's and the OEGB's are the ones I cant ever figure out. I have alot of them that I am not sure about. Thanks for your help. I appreciate it!!
