The dog listens quit good. But sometimes he escapes out of the house. Or they let them in the garden to pee cause they dont have have to walk with him (then he is always on a leach). The neighbours do try to keep the dog away from our garden. But not always succesfull.
Besides it would cost a lot of money to close our garden with a dogproof fence.
I see 2 possibilities:
1sth is to keep the chickens in. Have less chickens or build a bigger run.
2nd is to leave the situation as it is now. And be a bit worried if a chicken sleeps outside. If eventually a chicken doesnt return it did have a good life after all.
I just have to weigh the pleasure of free ranging against the risk of preditors.
