I have a Beautiful Americauna Rooster but he is young, My 7yr old americauna hen is wanting to hatch more babies her last set was when the nieghbors rooster got through the fence, I had Mutts, but Is she too old to hatch chicks she still lays every day for me. But I want some purebreds out of her to keep her line going, And I have a sharp looking roster to put with her need advise on putting her with the roo, and how old he will have to be. Thanks in advance for input on this.
