I have four chickens, they live in our backyard which backs onto the bush. We had a fox attack them in broad day light!! fortunately we have saved three of the chooks. Two of them hid in the coop, the other two flew into the backyard. We found one of them near our drive way (it was hiding deep in a bush not moving, just looking in one direction) and the other one cannot be found. Is there anything that can be done?? Please help!!
