Next time we build a coop/run/aviary/pen/poultry palace from scratch we'll redo our setup so we can do something like that. But our current set up has an open top pen with just the electric poultry netting. Thankfully my older birds are pretty savvy now and run for safety.
I totally agree. The electric poultry fencing was one of the best purchases I made this year for my birds. As much as I didn't want to spend the money. Not much besides a completely covered huge aviary will protect from flying predators, but the electric fence helps a ton and gives my birds...
A lot of the electric fence options are actually solar powered. Ours is. And its definitely been a huge help with foxes and coyotes. It's my third level of protection honestly. But gotta do whatever works for you.
My entire coop/run is surrounded by electric poultry netting fencing. We learned the hard way with a racoon earlier this summer as well as stray dogs, coyotes, foxes, etc. Thankfully now we mostly just have to worry about predatory birds during the day now.
I really like our electric poultry netting fencing too... its been a game changer here. I miss having my birds free range at my front door, but its definitely saved mine from a lot of predators.
Domestic mallards can fly. The downside to mallards is they don't lay a lot and they are small, so you're not going to get a lot of eggs or meat. I have two female mallards and I love them, but its because they are feisty and they like to go broody in the spring/summer and mine are great...
