Let it be. I have not yet successfully bottle/syringe-fed a baby bunny. A runt will be even harder. I now for some people this might sound cruel, but let nature take its course.

Depending on the breed, it could be a peanut. Peanuts are bunnies that are small and week and don't grow. They will always die and there is nothing that you can do to save it. Some peanuts are born dead, but some can live until they are about 1 - 2 weeks old. I have known to 2 that have lived a couple months!

i've got rescued quite a few infant bunnies. as quickly as the bunny is touched by ability of people the mummy won't shelter it. I purely went to the community save that sells puppy products and offered a animal bottle for around $2.00 and offered a pouch or a small can of bunny/kitten formula which runs approximately $4.00 - $5.00. save your bunny heat and be sure it eats, most of the bunnies finally died on me after some weeks yet a minimum of i attempted.

I would probably let nature take its course because what if it has like some disease...it would be better to let him/her take their own course and either it will grow or it may die!

what you do is wait for when the bigger stronger babies arent drinking milk, then put the weak one in its place, and soon it will become strong!!!!!!

let the mom do her thing wih them leave them alone
