[Reed Ranch]

I have five and a half week old chicks that I'm still not sure what I have they all look like hens then when I pick them up to handle them there wallets turn red then. so I have not idea if I have all boys or not. would the feathering give me a better idea?

They look really young//small so I vote towards cockerels...
