Awwww... pretty baby! I'd guess it's about 7-8 days old. Eyes will open soon. Don't be surprised if you get some "up" ears and some "down" ears! And you may get a "helicopter ears"... kind of hovering in the middle!
Perfect! You shouldn't adopt them out until they are 8 weeks of age. And yes, you should ask for an adoption fee so they don't wind up being "used" for the wrong things. I always give a 5 lbs. bag of food with any rabbit that leaves here. I tell people to keep them on my food for two to threedays, and if they are going to switch to a different food, to gradually start mixing the new food with my food, to switch them slowly. It is better for their digestive system.
If they don't have greens as babies, I tell people to avoid fresh fruits and vege;s until they are4 months old. And then gradually introduce them (like you would introduce new food to a baby).
Yeah, stuff seems to happen when we least expect it... or can afford it. As long as you keep them separate for now, it'll be good. And if she doesn't deliver another litter within 33 days AFTER you separated them, she didn't get pregnant again!
Keep in mind, the babies can and will be able to start breeding (even back to Mom!!!!) around 16-18 weeks... (4 to 4 1/2 months of age!). So get them in new homes or learn to sex them and separate them.
Edited to add: There are links
here to help you learn to sex the babies... But make sure you double check them as they mature... some young bucks will "present" as a doe when they are very young... and we all make mistakes. (We call it getting "Whacked by the Gender Fairy".... LOL!) I had "3" does together at8 weeks, suddenly at 12 weeks when I went to send one to a new home, it was a boy! :embarrassed:OOPS! Always double check. :shock2:
