My daughter went out for dinner with her OH on Saturday evening & the babysitter said the chickens were in their coop. They have a large coop in a run. The next morning there were only 2 in the run. She couldn't find the missing 2, they bought 2 more yesterday & today all 4 have been taken by foxes. I can't see 1 fox taking 4 chickens? Is it possible they got the scent from the first 2 they had. BTW they run free all day in the garden. The run was built as a pheasant run by some workmen working on the house but they also do these runs for people.
