Greetings all. Is this possible? I have a dozen (white egg) Brown Leghorns and a dozen (brown egg) Bantams, all free ranging together. (For no particular reason), I want to keep the Leghorns purebred. If I hatch only large white eggs and cull any birds that look like they might be a Leghorn/Banty cross, will the Leghorns stay purebred? Thanks.
