Why do the slimes keep teleporting out of their hutches

stardew-valley

I have ten Slime Hutches, almost all of them housing 20 slimes each, but for some reason every now and then I'll find a slime behind one of my hutches (always the same one), or even outside of the farm bounds. What's up with that? Is it a bug? Feature? Can I prevent it from happening?

According to the wiki:

It is also important to note that once the hutch has more than 5 Slimes, there is a 3.5% chance per night per slime to escape and disappear.

I'm guessing that's why you see a loose slime from time to time. As for why they sometimes appear outside the boundaries of the farm, I'd guess that's a legitimate bug (I've seen screenshots of other similar problems, like the player's pet being out of bounds).
