So after doing much research (maybe too much) I am a little bit confused on how to go about properly feeding a young rabbit. My rabbit is around 2 months old, and I know that the breeder was feeding him pellets (adult type), Timothy hay, and vegetables as an occasional treat. From what I have been reading, it seems that it is best to give 1 cup per 2 lbs of rabbit of vegetables (primarily leafy green). I have also seen where it says that rabbits under 6 months should have unlimited pellets and hay.
What is the best way to transition him over to vegetables, from solely pellets? Currently I have been testing out vegetables slowly (one per day), and he has eaten romaine lettuce and spinach with no problems. Today, I gave him a little piece of Kale while I was cooking and he seemed to like it. After inspecting his poop, it looks like the pellets tonight are a little bit gooey and stringy, but it does not look like hair, it looks like undigested kale that is kind of coming off one of the pellets (sorry for the gross details). Just wondering what this is a sign of I guess, does it mean that he is having trouble with Kale or that he needs more hay? He seems like he is pooping frequently, and it is definitely not like diarrhea, I just want to make sure that this is normal.
He also does not seem extremely interested in his hay, he is eating some of it, but I guess I don't have a grasp on how much he really should be eating is it better to mix it up with different types of hay rather than just timothy?
Thanks for all of your help! Any advice on young bunny nutrition would be much appreciated, doing my best, but it is always good to hear what other people have had luck with and also how to tell if the bunny is not tolerant to a certain vegetables?
