About five this morning I went to care for chickens when I noticed roosters not crowing as usual. Getting in closer birds that roost on pens were on ground moving about in relative darkness. No feather piles were evident. Head count indicated one short. I found a single dead pullet, American Dominique (Privett Strain). She was not dismembered. Upon closer inspection the skin and fat around neck was removed. Birds were roosting on blue tarps of this temporary setup. Ten American dominiques and three American games. Quality birds housed in pens. This group of pens bunched to limit effects of wind. I have been very lucky up till now with minimal losses. Mowing walking trails around pasture and woods may have enabled eaisier access for predator(s). Tonight I will use carcass as bait in live-trap. Will also sleep in hamock about 100 feet away. The perp will be apprehended and sentenced quickly. I am having some fun trying to stop the loss!
