Got my first pair, the little boy in front of me got the red heads.(natural). But I really liked the silver hybrids too, so bought those. I put them in a temporary pen that has 2" top net. It has chicken wire over 2x2 fencing . My female was outside this morning. Caught her , fortunately it was the runner duck pen and they didn't hurt her. I did find some breaks I didn't catch yesterday she could have gotten out of if she tried hard. What I am wondering is the 2 X 2 top net too big? I started to work on a new Aviary, but with the rain it may be two or three weeks before I can finish it. I could put shade cloth over it.... Also what size top fencing/netting is proper for exotics. I also want to get some whistling tree ducks, maybe wood ducks , teals or mandarins and who gets along with pochards? Breeder says he has many varieties together, but he has a huge aviary...
