Well, it turns out Putz is definitely a rooster. He is 15 weeks old and discovered his voice on Monday morning. He seems to dislike diesel engines and crows every time once passes by the house. Otherwise he is a fairly quiet rooster. And, he is a beautiful specimen of the Barred Rock, but a rooster is a rooster and we have already decided to rehome him.
Luckily, PeterC works with a guy who has access to a farm, and the farm is willing to take Putz. He'll be going to his new home Saturday night. I hope he finds plenty of willing ladies, lots of goodies to eat, and a long content life as a farm rooster. I'll miss him.
