I have a pumpkin hulsey about 6 months old and he crows so loud it's embarassing. I also have a barnyard americauna whose like Mike Tyson, quite a good size, hangs out with the girls and has a voice like a peep. I tend to think it's a personality thing. The hulsey pair are new and I'm trying to work with them like I did with my original group so we'll see. The routine that's been working so far is to have the birds look forward to treats like yogurt, baked potato, lettuce, tomatoe, fruit, etc when I come to check on them as well as stuff to scratch about in and take dust baths and lay in the sun. But the hulseys which are of the game bird category seem to have a different agenda altogether. Good luck!
