I just hatch my chicks because I think its cool to pair my Black Copper Maran with other hens from my flock like easter eggers or Welsummers, but the only thing is my rooster LOVES to make little roosters, this year I hatched 10 chicks and now that they are about a month old we can easily see if they are boys or girls and... we got 7 roosters and 3 hens.
