Thank you for your input!
However, his poops are of normal size and they are not strung together.
As for hay, I have been trying to get him less mature timothy just because I felt like he was wasting a lot of hay/eating less. He needs to have his teeth poss floated...he's next on the list once my horse gets his teeth done this month.
Anyway, I can't worry too much because at least he's pooping! It's just a bit odd because he has never done this before to this extent.
I would suspect that your rabbits issue is dental problems then. If he is having trouble eating hay because of his teeth, then this could very well be the reason your rabbit is eating his poop, to try and get more fiber, or even just more food if you feed limited pellets, as he can't eat the hay well and so is still hungry once the pellets are gone. He's not having trouble eating the pellets too is he?
If you haven't already, take a look at the front incisors to make sure they aren't causing the problem. If they are ok, then it is likely molar spurs or a possible tooth infection. One thing that may help with your rabbits teeth if it is molar spurs, is to try orchard grass hay. It is usually pretty leafy, so may be easier for your bun to eat, and it is high in silica, which can help wear down sharp points on the molars. And if it is molar spurs causing the problem and they aren't too bad, then the orchard grass may help enough that you won't have to get a dental done. If however, your bun still is having problems eating the softer orchard grass and isn't eating much of it, then it would be good to get your rabbit into the vet right away to have his teeth checked, as the lack of hay eating could lead to other issues like weight loss, increased dental issues, slowing gut motility and cecal dysbiosis causing mushy poop, and there is always the risk of GI stasis developing because of it, which will make things much more complicated and difficult to take care of. So if your horses teeth aren't really bad, it may be better to have your bun seen to first.
In the meantime, you need to make sure your rabbit is getting enough food so he doesn't lose weight and have another issue develop. If he won't eat much hay, even the orchard grass, but still eats pellets without a problem, one thing you can try is to buy some plain timothy hay pellets used for horses. You can usually get them at a feed store. The only thing with them though, is that they usually only come in large 40-50 lb bags, but they aren't very expensive. This can help ensure your bun is getting enough fiber from a hay source, and enough food until you can get his teeth taken care of. If he won't eat these and isn't eating enough hay or pellets, the other thing you can try is softening the pellets in warm water, to make them easier for him to eat. The important thing is just making sure he is getting enough food and nutrition that a secondary problem doesn't develop until the teeth are taken care of.
