If the male they used for breeding does have a sprig, keep a close eye and feel the combs also, on your growing birds. Sprigs multiply like wildfire (genetic fault). Do you know if they have only the one male or are there others they might be using for breeding? I'll tell you this, if you can keep more than one good male, do it. You never know when something might happen to your main breeder. Good luck with your birds.
Ugh, I caught a cold, I betcha at the poultry show on Saturday---incubation period about right, starting coming down with it yesterday. Haven't had a cold in a long time, hope this one doesn't hang around too long, I've way too much to do. I hope you didn't catch one there, Mary.
