Oh my goodness he actually looks pretty similar to my BYM cockerel, but mine has more gold instead of straw color. He’s also much smaller and has a bit more black showing. Mine is a mix of a black Silverudd’s blue (rooster) and a brown egg laying breed (hen). I’m not sure which one he came from, but the only hens which could’ve laid the egg he came from are RIR (unlikely), SLW, Barred Plymouth Rock, Buff Orpington (highly doubted), Sapphire Gem, or another breed which I can’t identify, but I’m not sure if she lays brown or blue eggs.
