Am I overreacting?

My mom and I tend to get into arguments over animal treatment on our farm. It's more of a hobby farm than anything, we don't make profit whatsoever, and have around 30-40 cows, 8-12 pigs, a herd of goats, chickens, horses and mini-ponies, and some ducks.

A big issue I've always had is that we almost never get professional help for our animals. We currently have some piglets, and the littlest one has a bad back leg. He has a sizable wound on it, and is constantly pressing it against the floor, I'd assume for comfort. Yet anytime I bring it up, I just get told that the vet probably wouldn't be able to do anything, and to not worry about it. The little guy's in pretty obvious pain.

Our old fencer wore out a few months back, and my dad found a used one at an auction. Problem is, it's way too strong for inside our pig barn, even when also powering our pastures. Just last Sunday, one of the other little guys got a foot stuck in the wire and was trapped for who knows how long. We got him out, but his eyes were bloodshot and he did not look ok. He's still kicking around now, but I found a good lower power fencer for the barn suited for pigs, so that something like that wouldn't happen again. Once again got told to just sit on it. On top of that, the pig barn itself was partially burned in a fire a few months after I was born, and is basically help up by wooden boards, nails, and hope at this point. I would cost us around 175K to rebuild it, which is way more than my parents are willing to pay, but the thing's chance of collapsing on someone is pretty high.

All in all, I'm just kinda tired of getting told that things are fine or that the vet/medication is too expensive when animals are hurting or living in not the best conditions. Am I overreacting, or do I have legitimate concerns? My mom likes to use the "I've been farming for years, I know what I'm doing" card, but that really isn't reassurance, and could honestly be the opposite if they still do things the old-fashioned way.
