You can definitely litter train intact buns. It won't be quite as easy, but most rabbits poop and pee in one corner anyways, so it shouldn't be too difficult.Not too long at all! Very valuable information. Can you litter train intact rabbits? I've read that they might scent mark a lot if not fixed. The set up I got is wire bottoms, but I plan to only use them for night time safety. I'll cover the bottoms and back so they have full coverage from the elements and predators. I'll also be adding a roof. I have a ton of little rabbit triangles, like little tractors, so I can put them out on the grass until we build a run. I am of the mindset of kindness when raising food and feel like a happy life is important even if it's a short one.
And once the babies are old enough that they can hop around the cage it'll be easy since they'll be starting young. Though there will be lots of coco puffs..
Sounds like you're going to have a great setup! Be sure to share some pictures, I'm sure other members could get some inspiration from you.
And I completely agree with you on being sure your animals have a happy life before being used for food. I plan on raising quail and chickens for meat in the future, and the most important thing to me is that they have a happy life.
