I don't know the answer to your question.
I do know that although Flemmies were developed as a meat rabbit, they have a less favorable meat to bone ratio than other meat rabbit breeds.
They also require a lot more space, special housing, and are often kept on wood slat floors as opposed to wire.
If your goal is affordable meat production, I would suggest looking at other breeds.
Although not nearly as large, Beverens have that "big bunny" look to them.
I only have one pair, and just bred the doe for the first time, but am expecting great things from them.
I spoke to the breeder of my doe, and she told me that this doe's mother has kits that reach 5lbs by 8-10 weeks.
