Just too many predators around here to have any kind of tame birds. There are wild - quail, turkeys, grouse, ducks and humming birds. When we had a garden - it was almost a full time job - keeping all the local wildlife out of the garden. We also have the FULL compliment of predators here. All the way up to and including - bears, cougars and wolves.
AND who thinks some kind of chicken wire enclosure will keep a cougar/wolf away from your chickens. Ha, ha
Over a nine day period - I had a cougar kill seven of my barn cats. He just ripped them to shreds and left them laying. Local game dept official identified the cougar by the unusually large paw prints left in the dirt.
We are missing the wolves, and usually no bears, but yes to everything else. Great fun to see. The few times that we have seen the mountain lions when we were out with our animals, it was clear from the reactions of our horses amd cows that the mountain lions were commonly seen. Their responses seemed to be along the lines of "Hey Ethyl! How is it going this afternoon?" No fuss, no bother, and we haven't ever lost any calves, despite having at least one den quite close.
Keeping animals out of the garden just got to be too much work between the ones that flew over the electric netting and the ones that dug under. We realized we were going to need to basically build a greenhouse with a perimeter foundation, and decided that as much as we adore home grown vegetables (tomatoes and cantaloupe here were amazing), on any sort of cost accounting, it wasn't worth it.
I have had birds in the past elsewhere, and I can't imagine trying to have birds here, though we do seem to have an orange feral parrot hanging around at the moment.
While we have smaller elk here, they do do a number on fences. Our perimeter fence is four or five strands of barbed wire with two hot wires to keep the horses off the fences.
The only time we have had fences broken though are when a former bull of ours (low line belted Galloway, 1200lbs+/-) would pick fights across the pasture fence with our neighbor's 2,200lb angus bulls. One day one of the bulls had heard enough, pushed through our fence, and then pushed our bull out into the county road, and kept him out. We found out when our bull walked up our front driveway complaining. I have to give him full markers for figuring out how to squeeze by our front gate on his own. It was a bit of a shell game to get the angus bull into our barn while getting our bull back to the herd. Our neighbors were really good about the whole thing, and came by a couple of days later to get their bull back with a suitable trailer. Normally, they were very good about letting us know when they planned to have bulls in the adjacent pasture, and we tried not to have our bull in our adjacent paddock at the same time. Mostly, we were really concerned about having our much smaller cows bred by their bulls, as calf size is larger determined by the bull, not the mother.
All the best,
Peter
