The kit on the right looks like a doe. I couldn't get a good enough look at the kit on the left, but I think it may be a buck. In real life, do you see a bit of space between the anus and the urethra on the possible buck kit? If so, I'd say it is a boy.
I could only see the top picture when I posted that. Not sure if you added other pictures later, our if I could only see the first one, for some reason.
I'm not sure if what I'm telling you is accurate or not so please don't shoot the unsure, under educated messenger. I was told or I had read somewhere that you can tell the difference between the does and bucks within the first day or so because the future does will have visible teats on their bellies were as the future bucks wI'll not. IDK :?: I will definitely check on the next litter that I hope will be here tomorrow sometime.
