My thinking is that by using my cross bred ewes with a BBB ram, I can avoid such problems as unseasonal breeding, however keen the ram may be, the ewes come into season when it suits them.
Similarly, this should also serve to reduce litter numbers to a manageable level.
Breeding for conformation is something I will have to watch closely, being prepared to cull rigorously anything that fails to meet my standards.
Feet would be a matter of routine, but I will pay special attention to this.
