Ok, I've been raising these rabbits for a full year now and here's what I have figured out. 1) They are freaky easy to raise! 2) The cost of feed is only an issue when you have 80-100 rabbits. 3) Cages,cages, cages! Start up cost including a covered shed to house them was right around a thousand dollars, get used to building them if you want to sustain yourself with rabbit meat. I have about 20. 6 are very large and I let them stay in there until its time to separate the babies from the mother. 4) Clean Birthing boxes thoroughly and give the doe at least a week in the cage with it so her scent can be transferred to the box, otherwise she will just have them on the floor of the cage ans they will die from exposure. 5) They cost right about $1-2 per rabbit in feed if you raise them for three months. leave them with the Mother for at least 5 weeks then sex them as best you can and separate them into growing cages. 6) It's important to time your litters 2-3 litters at a time, doing this will allow you to place kits from different litters in growing pens together and limit the amount of pens required. they will fight if you try to place other in after about a month. The males will fight if you grow them out for more than 4 months together. They become Sexually mature around 5 months. 7)I have 2 Bucks, one is a Flemish Giant Cross and the other a New Zealand. I have 11 Doe's they are all giant breeds ranging from 8-15 lbs. I breed them in 2's and 3 at time that way they have there litters on the same day or no more than one day apart. Rabbits will readily take care of anothers rabbits babies if they are roughly the same age, just put them in the nest. This is important if a doe has 12 and another has 8 you can put 2 in with the other doe and dramatically reduce the mortality rate. 8) They taste like Chicken!!! 9) Butchering them is hard for the first few times but after eating them for a while it gets a lot easier. They will jump around like a chicken even if you severe the head from the body! They are DEAD!! 10) Earmites- THEY WILL GET THEM EVENTUALLY! Buy a tube of IVERMECTINE it is a wormer for horses, put a drop about the size of a pea on the end of a Q-Tip and shove it in the rabbits mouth, usually you will want to dose all rabbits with connecting cages, just to be sure. Done your problem is over. Oil in the ears is very unreliable we tried it. Rumors of affecting the breeding are a myth, I know!! One Flemish I bought had the worst case I'd ever seen when I bought her and after three day she was cured and has continually produced babies. Do not treat rabbits within 6 weeks of butchering, it takes that long for the Ivermectine to wear off, this is why you only usually need to treat them once, oil method takes a week and then you have to do it again to kill any hatch, and then they still come back!! Take this advice USE IVERMECTINE! 11) DO NOT LET YOUR KIDS GIVE THEM NAME"S!!!! I have totally enjoyed the year I have had them, and, we have eaten close to 150 rabbits so far. If you have any specific questions feel free to contact me here and I'd love to help you out! Good Luck and its worth the time you put in.
