So i have 6 day old baby rabbits, 5 of them, but one is much smaller than the others,i gave him a millilitre of goat milk yesterday which is around 0.03 oz i think,and i gave him another today. He looks like what people refer to as a peanut,but niether of his parents are dwarves. Any suggestions on what i should do, the vet doesn't work due to the pandemic.
