I fed fodder for a couple years. 2 ft by 3ft rack with 5 levels of fodder trays (20 9in x 15in trays producing 4-5lb each) will replace 50% of pellets for about 20 adult large meat breed rabbits. Approx 8 oz serving for one meal. 100% fodder required over 1 lb per rabbit and was no longer cost effective nor did I feel I was safe meeting all nutritional requirements. That being said, once I switched to the higher fat Purina Show pellet $ savings from fodder disappeared since they eat less of those pellets than the 1.25% fat general pellet. So I've discontinued fodder for now but I may restart it later when I have more time because they really like it, kits weaned out very well on it, it got a lot more water into them and it improved the wool texture of my angoras.
