Feed it with a small syringe, bottle or eye dropper. In the rabbit world, a peanut means something totally different. If both parents carry the dwarfing gene, then there is a chance of the kit being a peanut. Three or four days is usually the maximum time they survive. Peanuts are ones with a double dwarfing gene and it is usually 98% fatal. A peanut will not survive past 12 weeks of age, a runt is just a small kit that will remain small all it's life. If the kit is eliminating waste then it is most likely a runt, peanuts usually have incomplete digestive/urinary systems. But I'm confused on whether he's a peanut or runt? I'm pretty sure that my new litter or rabbits are normal, but here's the explanation. I had put the runt/peanut in the nesting box with them...he's active, and doing fine. Irishbunny, not every runt is a peanut. For those of you who don't know, peanuts have both dwarf genes and almost always die, dwarf rabbits have 1 swarf gene and one normal gene. But the little REW is extremely small, a little more than half the size of the other two. I hope it is just a small one and good luck with your rabbits. However, I'm not very sure. The rabbits have all big tummies, and the ears are just normal. Also the buck should always be the same or smaller than the doe to avoid problems for the doe. I'm not sure if he's a runt or a peanut. This is a genetic defect in Dwarf rabbits that is thought to be either related to the dwarf gene, or it is possibly another expression of excessive dwarfism. Basically, a peanut is an abnormally small dwarf rabbit that dies within its first two weeks of life, but usually within several days of birth. while runts are just smaller than average. I'm thinking a REW? There can be lasting issues with some runts. Two will be either Otters or Martens, but one is pink. They are the color black, and the feet are normal. Source(s): I have six rabbits, three of which are fosters, I work with a rabbit rescue. This is why inexperienced people should not breed their pets. What do peanut and runt rabbits look like? Runt or Peanut baby rabbit? This is the 3rd rabbit generation, but I'm not so skilled. Are these dwarf breed rabbits? A peanut is a baby rabbit that has gotten two dwarf genes - one from each parent. Runts can survive, but will not have the characteristics of a peanut. Have just had a 2yr standard female Rex mated with a Mini Rex and she had 10 kits 2 weeks ago, with one being a runt judging that the head is in proportion as are the ears and legs, have tried bottle feeding but it wont have it so will let nature take its course. Ok I posted previously about if my doe was pregnant or not. She had three, all alive. There are many causes of runts and they aren't always fatal, whereas the double dwarf gene that causes peanuts results in a seriously deformed baby with essentially no chance of survival beyond a few weeks. Getting two dwarf genes is lethal; the baby affected always dies. With formula, you would need to find a good rabbit recipe and make it. But let's not confuse a peanut with a runt. You would need to give 3-4 feedings per day. Hi, I have read that overall health and nutrition plays a big part in litter size. Looks to be a peanut, has oversized head, eyes and ears, and is unusually smaller than its plump siblings. Turns out she definetly was. This is not to be confused with a runt. Also it is not a good idea or good husbandry to breed 2 different breeds of rabbits.
