I started out giving alfalfa hay to each of my buns because “they” say it’s best for the young ones because of the calcium. However, I recently read a couple of veterinarian articles about how alfalfa hay is too high in carbs and crude protein, and they avoid giving it to their own bunnies, even the healthy ones. So just the other day, my half-pack of alfalfa hay, purchased barely two weeks ago....I noticed it had some little brown bugs in the bottom half of the packet ~ needless to say, I threw it out, and won’t be buying it again. My little sunshine bun is still on Timothy hay, but no more alfalfa/Timothy mix. Will offer orchard hay as treats eventually, but she’s on Timothy hay indefinitely, and a small portion of Timothy hay-based pellets, and fresh greens daily.
