I’m certainly not an expert and I’m sure some of the forum leaders will respond soon but this is what I understand to be true:
Young rabbits can handle a little more calcium in their diet, so I don’t think that will be a problem for a short time. Oxbows calcium level in their young rabbit food is 0.50-1%.
Since Todd (who’s adorably cute, by the way!) is only 5 months old, it’s definitely ok for him to be on the alfalfa meal. I believe I even read on the Oxbow site (or back of the young rabbit food bag) that buns less than a year old can be on alfalfa pellets, then switch to Timothy after that. (I need to find that info again to be sure, and I hope one of the leaders-or members with an Oxbow bag handy-will respond to that so that we have the correct info!)
The fiber content of your food is less than the Oxbow food (theirs is 22-25% fiber) so thats something to be aware of. Is he a good hay and veggies eater? Does he still get unlimited pellets? If you want to see all the Oxbow nutritional info its on their animal health website.
I know this may not be much help, but maybe some of the info will be helpful. Sorry I don’t know more about it yet. I’m new to the world of indoor buns (Frank N Beanz are 4 months old now, so I’m definitely still learning too!) Good luck!
