Before i make their permanent home in the yard, i wanted to run somethin by you folks. I'm planning on putting the pen in a pretty shady part of the yard that only gets direct light for maybe 4 hours a day. With 90-100 degree days in the summer, i dont wanna come home to cooked ducks. With it being shady a lot, theres a particular moss thats growing thats really soft and i figured theyd enjoy it. Are there any mosses that can hurt ducks or any reason why moss being there is a bad thing? Its just a portion of it, maybe a quarter or third of the pen. Also, i have clear roofing. It wont get a ton of direct sunlight until around noon. Am i wrong to think theyll be out of the house during this time so the heat wont matter? Home depot may not take it back because its been on the ground in the rain, but i can try if its that big of a deal. Thanks!
