I know its possible. I built a barn to make my base look rustic and tamed boars and bred lots of them there. Once I got up to about 20 boars they would clip through the walls when I loaded the base in so I built an exterior wall around the barn. When the troll raids happened I changed the outside wall to an earthen wall. When I got to the mountains I partitioned the inside of the barn off and put wolves on one side and the boars on the other.

As long as you feed them they will continue to breed until they start spilling out of their enclosure due to the number and clipping issues.

The same applies to Lox. I saw people that said that Lox need lots of room and stop breeding if there are too many in a certain area and that is also provably not true.

Nothing wrong with being a crazy mom. I can speak from experience that a gamer mom is cool with her kids and will keep a gamer dad happy.
