I grew up on a farm with cattle, so fences were a vital part of the work. I didn't ever mind doing other work related to the farm, but for some reason I didn't even enjoy putting up new fence or repairing fencing.
It's probably good that you've introduced your kids to it early, haha.
Free animals are always great. My parents got all sorts of free chickens, turkeys, pheasants, and guineas when I was growing up. We had a nice variety of yard birds that helped keep the bugs down and laid eggs. As long as you've got the space for them, I understand why you don't turn them down!
Thanks for sharing!
