Came home from work sat to be told by new neighbours that one of my hens had got into their garden and she heard dog barking and found them looking at each other,so put hen back over fence.Apoligised for hen getting in garden,never happened before. I have a fenced off area in the garden but fence between us is inly 4ft high,but in 2 yrs they havent ventured over. As it was dark got my torch and checked coop and sure enough all inside. This morning on letting them out could see my silver sussex had been bitten and on close inspection was horrified to see flesh wounds an inch accross on both sides of her back. Such a pretty hen and docile,she will have crouched down and dog grabbed her no doubt,I have cleaned wounds and sprayed with scepti-cleanse and anti-peck and given her a tonic in syringe.Spent the day making fence higher and adding reed screening,i rent so cant change the fence. Trouble is every time the b..... dog comes running out into garden and barks non stop at the fence and she is absolutely terrified and goes in nestbox. Had no such problems in the 2 years with hens but didnt bank on getting new neighbours with a yapping dog. I am too worried to let them in run while im at work tommorrow but their covered run adjoined to coop is only 6ft by 6ft and worried the other hens will attack her. Didnt realise how attatched i have become,she is the most friendly hen and so timid,i hope she survives.
