yep, that sounds like what I did, sit for hours seemed like just watching them.
Tell ya something cool, when I'd drain the ponds and clean them out, obviously they all had to come see what the heck I was doing, but in these south Georgia summers, once they were filled back up with clean fresh water, well, I'd usually get in there with them to cool off. Mine were all pretty deep for duck ponds, 3 foot on average.
Would just kinda sit still for a bit with my head out, and they just swim right past you like you were part of the pen. Sounds silly I know, but it was pretty cool actually, out of the water, you know they can be a bit skittish, but when you got in with them, they'd just go right up to you.
Get you dad to do that next time he takes pictures, oh and get one of him doing it too, LOL
Waterdog, oh yeah, I didnt mean to say they werent hard for yall too, but it seems that the vast majority of the birds produced do come from yalls area in general. Kinda like the treeduck here. I got tons of birds, my originals, from Willard Henson and Charles Kamm there in Minnesota, and those 2 could flat breed some waterfowl regardless of what kind. Willards, I know was about 7 acres of natural ponds all covered with thick heavy grasses (like shawn says). Another very successful one up north was Ed Jordan in Maine, he and his wife always did some excellent production too. Just something about those northern climates especially with the North American species.
Dont think they like 110 and 99.9 % humidity too much
