Hoping for some wisdom from dog training experts here. We have 3 hens which we keep in a section of our back garden. Neighbours 5 doors up have a field spaniel who I think is about 6 months old. It first got into the garden last week and attacked the hens. The kids and I were there so scared it off - it was very upsetting and traumatic. One hen missing a large chunk of feathers and some bite marks but nothing serious. Chickens put in their small run as precaution. Dog returned the next day and the day after. Owner only accepted it was their dog when I showed them a photo of it in the garden!
They said they had fixed the fence, we tried to secure our side, chickens let back out. Dog returned again - made a new hole in hedge/chicken wire and attacked again. Chased off quickly but one hen with lots of blood and all tail feathers removed. Told neighbour and gave them vet bill which they agreed to pay.
They assured us fence is really fixed this time. DH buys more stuff to Fort Knox our end but chickens still in run. Neighbours children left the gate open today and the dog came straight round.
Obviously now the dog knows they are there, he won't give up. I suggested to the owner that they should look into training the dog to leave them alone but he poo-pooed the idea. Could a spaniel who doesn't live with hens still be trained (with our cooperation) to stay away? All the examples I've found online are of people who have dogs and hens together all the time.
Sorry that is so long - must work on my ability to condense information!
