Of my 10 RIR chicks, there is one in particular that has almost white wings. Then there are a couple others with more cream color wings, and the rest have wings the same color as their fuzz. They are a week old today. Do these colors indicate anything? Like sex, or a possible mix breed? Thanks! Oh, and I think I'm already hooked. They were eating out of my hand! Oh, and I bought them meal worms and crickets and they went f'n crazy! So fun to watch!
