So my boys I think are starting to hit puberty. Every time I walk up to the pond August (my brown drake) puffs up really big and squawks at me. He's got Trudy (my white/silver) drake doing the same. Here's a video. What's he doing? Also, he's showing a lot of head bobbing. Is this a precursor to mating? My only female is my fawn and white and I've been contemplating getting rid of her and just having two or three males, but I didn't think I'd need to this early. They're about 2 1/2 months old now.
