The reason most people don't raise flemish giants for meat is b/c they grow slowly. their feed conversion ratio is not a good as say a NZ or a cali. Those breeds gorw that fastest in the least amount of time with the least amount of feed. both those breeds can be raised for either fryers or broilers, one at 8 weeks, one at 12 weeks. Beyond that, they do not convert their feed as well. also , they are bigger boned than the other two breeds, meaning they have more bones.
that being said, if yo want to raise them for meat, They will still be good. they will just eat more to get to the weight you want them, and then alot of the weight will be bone.
As far as breeding lionhead doe to a flemish buck, it is not recommended to do that, as the small doe will very probably have a difficult birth due to the fact that the kits will be bigger (b/c of the flemish buck) I would seriously reconsider doing this. If you want to get a smaller buck for the lionhead, that would be great. Either another lionhead or a minilop--that would produce a lionlop. Andthey are popular for pets.
Also, rabbits thrive better in the cold than they do in heat. I have a pregnant doe right now, and have had many litters in the dead of winter. It wa more difficult to breed in the heat of summer.
Good luck with your meat raising endeavours.! there are quite a few rabbit breeders here if you have any questions or concerns.
