Yeah, she had so many baby snails she had to get some smaller separate tanks for them. Google tells me chickens can and may enjoy eating snails so maybe I'll try that sometime. My friend's snail "community" has been captive for nearly 2 years so not at much chance of parasites or whatnot compared to wild ones.
We found out that our chickens seem to like minnows too. We got some feeder minnows for our garter snakes and they LOVE them. One in particular can be seen watching the water bowl for awhile, hunting. We threw some excess into a shallow water tub in or chicken coop to see what happens and they were gone a day or two later. I know I can get dried minnows (and shrimps) from a chicken treat company I usually buy from, but fresh ones give some enrichment to both my scaly and feathery kids.
Edit so I don't double-post:
It pisses me off when I see someone post "I just got this cute snake at a reptile expo! Can anyone tell me what kind of tank it needs or any tips on care?" Like, you should have that in mind BEFORE you ever get a snake wth. People kept telling me blood pythons were "hard to take care of and aggressive" before I got mine. But I researched for several months and had an exact idea of what tank to set up and how to feed her before even going to an expo. And she's the most docile snake of all my friends. Hech, it even pisses me off when people think you don't need any preparation to get a dog or a cat.
