I bought 30 pullets from Ideal and they are 4 weeks old. There's been one or two with larger combs, that I've been wondering about, but this morning as I was walking out to the pen, I heard a weak throaty crowing sound. By the time I got there it had stopped, so I don't know which one made the noise. Anyways, I was hoping I'd get at least one rooster in the bunch, but now I need to figure out who the culprit is??
