First time to BYC and I am not sure which category this would fall under. We have had 12 Red Sexlink chickens for about a year. Last month our 2 yr old black lab got into the coop/run and killed 6 over the course of a few weeks b4 we caught him red handed. Dog has been relocated w/ someone else. We have 2 other dogs, but generally that aren't as interested in the chickens. We got 12 new pullets last week and now we are up to 18 Red Sexlinks. My problem is that the chicken run is in a wooded area and the hens have pecked away at every little sprig of grass. The chicken run looks more like a pig sty than chicken run. We have adequate grassy yard & wooded land for the chickens to free range during the day. We have about 20 acres available to us maybe 2 acres grassy and the rest wooded. I am worried about our 2 dogs bothering the chickens. They do have wireless collars on which keeps them just around our house and the hens would have lots of space where the dogs couldn't get to them. Will the chickens learn where the dogs are and stay way? What should we do? Also if we let the chickens free range how do we keep them out of our garden and away from our berry vines & bushes? Any help would be greatly appreciated.
