The reason why Flemish Giants aren't considered a meat breed is because of how they grow, and how long they take to get decently fleshed. When their at the normal 'fryer' age their all head and ears, gangly and bony. While little Cali's and NZW are busy putting on muscle Flemish are busy growing their frame. They do not flesh out until 16-20 weeks, sometimes even older, which is just fine for a home producer, but then their no longer a fryer but a roaster. Their feed to meat conversion rate is another point to consider, they eat a lot, you have to feed them far longer, their just not economical as meat rabbits. Their also well known for the does losing fertility early, they start to decline at about the 2 year mark, bigger they are the sooner they stop producing. I've been told this by Flemish old timers and have seen it first hand as well. There are huge differences between the colors in size and conformation, Sandys and Whites are largest, then Fawns, then Light Grays, Blacks, Steels and lastly Blues. I had Light Grays, mine averaged 14-17 pounds full grown, most at about 15, which is considered small. What was great about my Light Grays though was their fertility, they bred well until 4 and produced large litters, I was the envy of my Sandy Flemish owning friends. Light grays can't compete with Sandies on the table though, although that doesn't matter to you. I really can't suggest them as a meat rabbit, because their just not a meat breed, and its going to cost you so much more growing them out. Granted, all rabbits are made of meat, but there are better meat breed choices out there. I also had a hard time selling them as pets, although I marketed them heavily and sold at shows I still never broke even on food. Sadly thats why I let them go, the feed bill was killing me. I could feed 5 Mini Rex for what one Flemish ate, and I could sell Mini Rex all day and night. Other things I can think of-they have a strong musky rabbit smell, much stronger than other smaller breeds. They are clumsy mothers, I always expected to lose 2-3 kits a litter to being stepped on and squished. Their not all gentle giants, they leave big nasty scars. They do need solid floors, and have to have their cages kept very clean, flystrike can be a big problem in the summer, as they tend to be sporadic groomers and often can't keep their big butts clean. Minimum size cage for a breeding doe is 3x5 or 4x4, she needs room. Sorry to be such a downer, but I bred them for 5 years, long enough for the honeymoon phase to be over and then some. Still love the darn things though.
