Bunnbunn, unless you are highly experienced at hand raising kits or have a doe that can feed them I suggest not doing it. I hand raised a 7 day old kit that is now 8 weeks old. It is a huge commitment emotionally and financially, my vet bills have been in excess of $500 over the past 6 weeks and my bun continues to have GI issues as a result of an early weaning. I wonder if they are trying to rehome the doe too? If that is the case I would take the whole group and place them when they are the appropriate age. Where are they located? Perhaps there is a rabbit raiser/ rehabilitater you could reach out to and they could intervene.
Edited to add: you stated that the age isn't posted, perhaps they are of weaning age and that is just an old photo. Two week or bunnies are ridiculously cute. If you are interested in one of them, I suggest reaching out to them then diplomatically suggest that they not sell the for 8 weeks if they are younger.
