I lost 5 chickens around 6 am. 1 full grown welsommer roo, 3 buff orpingtons, and 1 americuna. Found only small bunches of feathers but they were in separate areas of the yard. 1 clump about 175 feet from their covered run in an area they never free range to, a flurry of orpington feathers on the other side of the house,300 feet from the coop but an area they range in. And no sign of roo feathers at all. I know there is a red tail in the area but im confused to lose so many birds all at once in different parts of the property. Also, there were signs something went under the coop to access the run and the terrified chickens broke out through small open corners that hsdnt yet been wired. We resecured the run and no further losses but i cant imagine what this was. 5 birds all scattered around a 3 acre lawn..any ideas?
