I have a trio of grays that I've been thinking of getting rid of. They are exhibition / breeder quality, and I paid $200 for the trio last October. The drake has not fertilized a single egg all season, and I have never seen him breed the girls, I think it's the size of the pen and size of the pool they have. One of the females (the smaller of the two) brooded her own babies last year. I purchased them directly from Mahlum's Waterfowl.
I don't have any pics of them right now, they are filthy little beasts who hate baths.
The little girl is 2 this year, and the other pair is a year old.
