You will be able to keep chickens and dogs. You will just have to fully enclose your chickens, as Im sure you know. It does take a lot of time and energy to train the dogs to leave them alone, and with there being three, you may not be able to break through the pack mentality. So, just dont free range your chickens. You can build a very nice large coop and yard that is fully secure from your dogs, and keep both. Obviously, you under estimated your three dogs, and it is unfortunate that you lost all your chickens, but you can start again. Im not trying to be complacent about the loss of the 21 chickens, but, its not worth getting rid of your dogs over. I wouldnt get rid of my dog if he attacked a chicken again. I would just take better measures to avoid it, and now going by your dogs track record, you know how to do that. Im sure you are more attached to your dogs.
IF you put up some good fencing and THEN start working with your dogs, it will be fine. Are your dogs trainable? I mean I have two dogs. One is trainable, one is really dumb. The one that is really dumb is small and always inside and just isnt a threat to the chickens, the smart one is the shar pei lab, he is the one who killed the chicken in the first place, so we worked with him over and over in levels. But like I said, he is trainable. Sometimes you just cant get through to them. However, if your fence is strong enough and they are fully enclosed, it won't matter. Good luck.
