With the addition of inner fencing and a gait at the end of the driveway, that problem should now be solved. One hen was killed. The other one has survived but was pretty well "skinned." There is a patch about the size of my open hand that has no flesh left, plus severe puncture wounds here and there. She doesn't seem to be in pain any more, is eating and drinking, but I'm not sure if she will ever recover fully, and if she does, the thought of a rooster mounting her gives me nightmares!
In the meantime, I have young ones growing up and eggs in the incubator, so in the spring should have my flock back up to speed.
