He looks like he’s only 4 – 6 weeks old
So he’s way to young to be getting neutured anytime soon you should make a vet appointment and talk to them about it usually rabbits get neutured between 3 to 6 months of age depending on the buns maturity rate
Also, he’s a bit to young to be having vegtables yet as it could upset their tums at such a young age
He should have unlimited hay and rabbit pellets right now (And water!)
And at about 12 weeks (about 6 or so more weeks) you can slowly start introducing veggies, as a rule of thumb, one new veggie per day to see what might upset his stomach cause all buns are different! And rotate veggies so he gets a nice variety
