Well, i raise 3 breeds of rabbits (New Zealand whites, Dutches, and Harlequins) and will be expanding my rabbitry this spring. I've let rabbit run with the chickens, and have never had a problem with chickens hurting the rabbits, though the top chicken will always come and peck them a couple times when i put them out in the yard. The worst problem with ducks is they are messy, and that means the rabbits will get dirty. Oh, chickens will also happily eat the baby rabbits.
So, i'm assuming that you will be raising the rabbits all together? Or are you keeping them in cages? If you are keeping them in cages,you will be totally fine, just make sure the chickens can't roost on top of the cages and poop on them. Also make sure that newborn babies cannot slip through the wire on the sides or bottom. If you are raising them all together (colony style) then there are more problems that can arise. First, if your coop a dirt floor? If so, they may dig out. I promise you, they are excellent diggers. Second, not all rabbit s get along with each other. I have had some rabbits that get along just fine, and others that will start fighting the second i put them with another rabbit. The boys will fight if you have more than 1. You will need 1 nest box for each rabbit, and 1 or 2 extras just in case.
If possible, i would make a simple stall off to one side of the coop so that the chickens or the ducks can not get into the nests.
I would also keep the buck in his own cage, or he will breed your does so much, they will never get a break and their bodies will not last as long. Also, you could be easily swamped with way to many babies. With the boy in a cage, you can control when each doe gets bred, and which one gets bred.
Rabbits can't eat the same food as chickens or ducks, and will need their own place to feed. The will need rabbit pellets and must also have hay to keep their digestive tract moving.
How many does your pet store need? Are you going to just raise them for the pet store, or are you raising them for meat too??
Keep in mind that 1 large doe (like 6+ pounds) can have over 12 babies per littler. That is a lot of babies to find homes for. Smaller rabbits (2-5 pounds) will have 2-6 babies, which is still a lot to find homes for. 1 does can be bred 3 times a year (they CAN be bred more, but it is hard on them). 1 buck will service 3-4 does as well.
Keeping rabbits cool is fairly hard. Rabbits have a lot of fur, and the only way to cool themselves is through their ears. I fill up 2 liter soda bottles with water and freeze them to keep them cool. They are fine in winter, but it is the heat that can kill them. Replace the waters at least 2 times a day (Have 2 soda bottles per rabbit so you can swap them out). If you have room and not a lot of rabbits, being in texas, you may want to find space in your house where they will benefit from the AC.
well, sorry that was so long
Good luck. If you have any more questions, feel free to ask
