I'm late to this thread party!
We have ducks, geese and chickens, miniature horse, and 100 fancy pigeons, the plot has a pair of miniature dachshunds and a young Spanish mastiff livestock guardian. The daxxies are great watchdogs, and are totally safe around the poultry, it didn't take long for them to accept each other, but they will eat eggs if they get chance. They are also good vermin control, mice, rats and squirrels.
The mastiff is my new baby, excellent around all the livestock so far. An amazing pet, great around our 16 month old, albeit a bit clumsy at this stage, she is a huge breed, but very good in the house, and an excellent guard dog.
We do need very sturdy fencing though, the daxxies would go under and the mastiff would go over or through.
The hope is for goats and sheep later this year/early next year, so time will tell. We have foxes and badgers around and so far so good.
