so I have 4 standard rex rabbits... one doe is by herself two jr does are together and the jr buck is by himself. the two does together are losing weight, i looked at them today and was shocked at how skinny they were. the doe alone is fine if not a little fat and the buck is fine. thing is that, theres still food in their feeder, water in their bottle and hay in their box. the other buck and doe finish their food every day and usually about 1/2 of the water, which i refill anyway. any ideas??
