I posted about this same baby bunny about a week ago. He is a mini Rex and was the runt of the litter. At 3 days old he almost died because of how badly dehydrated he was And he also had neon green poo. I decided to bottle feed him because him, because he would not try to eat on his own. I have been feeding him since day 3 and he is currently 18 days old. He has been gaining about 4 grams a day. He is very active and loves to eat! I have tried to put him back with his mom but he gets cold or doesn't get a chance to eat because his siblings push him away. I am feeding him a mix of goats milk and goats milk powder. The total fat and protein content is 8%. When I changed his formula the color of his poo is a white? Am Idea why? The picture below is him beside on of his litter mates. How can I increase the calories, fat and protein? Has any had this problem? So you think he will live?
