Does anyone on this thread have any thoughts/ suggestions as to how to keep the rabbits from wasting their hay?
I’m not sure what to suggest for the OP without having the ability to get rabbit specific pellets (Purina Pro Rabbit “grain”).
Our rabbits love their Timothy hay.
My friends’ rabbits will only eat oats hay (again, not straw)
But we also both breed, and offer hay as much as 100% in front of them as possible, plus measured pellets daily (less in the summer heat, more in the winter cold)
But the hay waste is an applicable question to this thread, I think

Not trying to hijack the thread. Just trying to (learn as well as) help!
I have slow feeders on the side of hutches, and also always offer some “free” hay inside when I re fill the slow feeders, usually 2x daily.
Pellets daily as I mentioned, not many other treats offered here at all.
I just hate allllll the wasted hay that’s hard to find and very expensive around here :/
I can buy 3-4 (2 string) bales of local grass hay for my horses for the same cost as 1 (3 string) bale of Timothy for the rabbits

The oat hay is a little more affordable- but my rabbits have better body condition and poo w the Timothy and pellets ...
