For treats, it varies per rabbit, as sugar content is a concern, as well as supporting selective eating habits. Rabbits have different bars of expectations— for some rabbits, getting two treats per day heavily decreases their hay consumption because they’re waiting for more treats. Wick is limited to 1 Oxbow Veggie Treat per day, which he knows exactly when he gets it. I would definitely not go beyond 1 treat per day, every day. If it’s 2 treats in one day but it’s not a regular thing, then it’s quite harmless.
According to House Rabbit society (http://rabbit.org/suggested-vegetables-and-fruits-for-a-rabbit-diet/), it’s 1 cup per 2lb of rabbit, which aligns with what I give Wick. You can measure it out, but after you get a good idea of what the quantity looks like, feel free to eye-ball it. You’ll want to observe how many of the greens are high-calcium, because that may cause issues. Also, you want to make sure she’s still eating hay with all those veggies, but she seems like a big rabbit with lots of eating room, haha. Wick is at his max weight of 2lbs, so I cannot speak from experience!
