The answer is yes. A rabbit produces two types of feces. The first one is the hard, round pellets you normally see which is sometimes called "day" feces (or "hard" feces). But because the rabbit has a digestive tract where lots of fermentation occurs in the hind gut, the rabbit will produce large, grape-like cluster pellets called "night" feces (of "soft" feces). Soft feces are very rich in B-complex vitaminsand high quality amino acids. The rabbit may consume this soft feces, apractice called coprophagy, which is part of a normal behavior pattern. Several other species also practice c oprophagy, including horses and ostriches. 4. Should my bucks be fed the same way as my does? If you are using your buck for breeding, the answer is probably no. Normally, a buck is used about 10 times a year per doe (assuming a 35 day rebreeding interval). Ten does would mean he is used about twice a week (10 does X 10 intervals divided by 52 weeks). All these numbers indicate that he is not very active and has a tendency to become fat and lazy. You can use the same feed that you give the does but make sure that the buck is given enough feed to prevent him from becoming too heavy.
