I think Maxwell will be the only one to do time for anything tbh.
I had a couple ducks for a while but they fouled up the water so quickly that my chickens got infections in their feet and lost toes. One of them had literal stumps for feet and eventually died. I had to ditch the ducks but yeah, duck eggs are undoubtedly superior. I'm not really set up for full free range either. Not enough bullet proof fencing. Foxes, coyotes, raccoons, and hawks everywhere. I have to maintain constant vigilance with heavy rocks around the base of my chicken run and even fencing around tree trunks so the foxes can't jump into the pen off them.
Wish I could fully free range cause I'd have to mow a lot less. Perhaps in due time.
