No I don't think they are seramas, they look a little too big to be Seramas and the form isn't quite there. The first roo is splash colored and I don't think seramas come in soilid splash. The other is a hen. They both look like game/crosses to me.
I'm definitely not the best at guessing breeds, but the top one looks like some kind of game bird and the bottom one looks alot like some of our EE's. Hopefully someone who knows for sure can answer.
