Welcome-Very cute bunny!!
Sometimes people aren’t always honest about how old an animal is when they re-home, adopt or sell. Where did you get your bunny from?
I’m no expert but I’d think your bunny looks 6-7 weeks, should have been with mom a bit longer (8 weeks is of course the minimum for mammals to be with mom so they can learn proper behaviour and get all the benefits of nursing and socialization)-it’s unfortunate whomever you got your bunny from wanted to sell/adopt/rehome so young. It would be very important for you to keep a very close eye for any health issues as such a young baby is vulnerable-you’ll want to watch for any eye or nasal discharge, and make sure he/she is eating, drinking, peeing, and pooping -pretty much constant eating and pooping, drinking and peeing is often. Feel Free to ask as many questions about normal health status as you learn about your rabbit, so you can make sure he/she is healthy and decide if he needs an urgent vet visit.
As for a name…welll until you know the sex for sure it’s hard, but he’s definitely a black dutch rabbit-dutch rabbits are incredibly smart and very good looking bunnies. With the colors I’d almost think a ‘james bond’ name is in order-you know for like a pun on the tuxedo look. Like, James, Bond, Tux, Ace (of spades) ..etc
