I’m so very sorry your bunny has passed away. As mentioned by LBJ10, breeding is not a topic allowed here at Binky Bunny.
• Accidental Litters: We do not have the experience to advise you, and we discourage ongoing threads on the matter because the information then goes out to google search results, inviting more of the same. Only a couple of members have some experience with this, but we are unable to make sure the advice given is reliable; we are not a site or forum that has a wealth of experience in this matter and it would be better for your bunnies to find reliable resources for pregnant/nursing does and their babies. Please visit Resources and scroll to “Oops Surprise Litter”. Other forums like Rabbitsonline.net, that cater to a broader range of experience, may also be able to help. And of course, be sure to seek vet care and advice. Do not post pictures of the litters, unless you plan on keeping them.(or whichever one or so you plan to keep). Do not use the forum to give or sell bunnies as well.
I hope your vet is able to help your bubs and I wish you and them lots of luck.
