Best mothers are american games PERIOD! They will die to protect their offspring. I have seen them fight dogs,cats,owls hawks weasels racoons, snakes, and you if you harm one of her biddies{.For you Yanks, thats southern speak for chicks} If you cross them into any breed they will increase the crossed bloodlines ability to resist disease, and make them more hardy all the way around. Try them, you will see what I mean. I tried it 40 years ago and have not looked back. It is not uncommon for them to sit, raise and wean two batches a season. I have also seen my friends give a new mother 50 biddies to raise and not lose a one!
