Yes. The chicken industry is the most egregious example, but all industrialised meat production suffers from abuse problems to some degree.

Ever been to a commercial pig farm or looked into the conditions at commercial milk production facilities?

I'm sure there's a range, and I've no strong feelings in either direction on the matter (had great wagyu beef last night), but I do believe there is probably a good bit of inhumane treatment in our food supply chain, sadly enough.
