One of our supposed hens started crowing the other day. It wasn't that much of a surprise - even though he was supposed to be a hen, it was clear for a long time that "she" might be a "he". What does surprise me is that this rooster came from a batch of sexed day-old chicks. They were supposed to be hens, but obviously sexing chickens is not an exact science. Because of that, most chicken breeders have a return policy for roosters.
I say they have a return policy - I went and talked to the neighbor I got him from and found out he ordered them from a hatchery in Ohio - not exactly a returnable rooster. So, once again, I have to figure out what to do with a rooster. He's not a problem right now. I hear him crow early in the morning, but he's pretty quiet - I haven't heard him during the day, but Robin has.
I'm not sure what we're going to do with him. We'll probably end up putting him on Craigslist like the other roosters, but until then, we have a pretty large chicken running around our yard.
