My husband made a predator proof chicken tractor - about 6 foot wide and 21 foot long. We picked up 6 hens on Saturday and they loved it - each laid an egg on Sunday!!! My daughter runs the farm during the week and brings her 2 large German shepherds to work with her. The hens are terrified and won't come out of their coop if they are anywhere near. (doesn't help they run full force towards their run. We are working on them - but...) My question is 'Will the hens finally realize the dogs can't get to them and learn to feel safe?
