Welcome to BB! =)
First off, with them being so young I would definitely separate them. Did you get them from a breeder? I would wait until 3 months then take them to a vet for a wellness check and to be sexed again. It’s EXTREMELY difficult to sex a rabbit at a young age and we’ve had many a people on BB bring one home thinking it’s one and find out when they take them to spay/neuter that they are not the same sex as they thought! LOL. It’s a necessary precaution. Separating them will also help as they grow into themselves and hormones develop. It’s very typical for babies to begin fighting around 2-3 months and need to be separated as they can really become aggressive little things until spayed/neutered.
They are gorgeous little buns though! Wait until 12 weeks to introduce veggies and then introduce slowly, one at a time, so you can tell if any specific one bothers their little tummies. Good luck with your new buns! Feel free to ask any questions as you have tons of people to give good answers!
