I wouldn't say feral, like I'd spend time with them, feed them treats, and some food, but I want to spend as little time as possible working to get food for them except to get some to feed them for treats and bonding, and winter feed. Essentially, let them feed themselves in all seasons but winter.
I was considering pollarding trees, if that's the right word, and getting tree hay, and setting some land aside for hay/silage. Just reducing my overall workload. I feel, but don't know, that letting the animals provide for themselves may reduce their time to slaughter, but saves me time and effort. I'm not concerned with getting them up to size quickly, just long term sustainability, where they could potentially survive without me, if that makes sense.
