Hi Marty! Welcome from another Portlander (er, Clackamite, if I'm being honest). I'm envious your dogs don't mind your chickens. We have one documented chicken killing dog - an Aussie who has killed two chickens in his life (years ago, not ours). He ignores them in the coop now, but when we first put the coop up he'd dig around the edge or mouth the chicken wire. Our other dog - an Aussie/Gordon setter cross - is an unknown entity so better safe than sorry.
Anyway, hope to see you around!!
