I would have the police there and file a report and then have the neighbors replace the birds. Sorry but the dog has no business on your property and it is up to the owner to keep his dog under control. Would also have them pay for the hatching eggs too! What kind of Peas were they?
Oh I am so sorry to hear such sad news. My neighbor's dog came over last winter and killed my two chickens who were my pets, so I know how you feel. I went over and told my neighbors what happened and told them to make sure he never comes over again. Luckily, he never did and has now passed on so I felt safe getting my peafowl. My thoughts are with you tonight.
