boy the fox and coyotes have been a real scourge this year for us too..we had 25 laying hens and we are down to 6 over the last couple years assults. My husband calls that hedge line to the woods the vietcong of chickens..we are installing a much bigger fence all the way to the garden..the bigger coyotes jump in and right back out , they test weak spots in the fence..it is 4 ft..my husband rescued a hen from a fox this last spring, she was really torn up and we had to do a lot of work to fix her back up, we thought we were going to loose her too but other than scarred and feather damage she is fine now..just this morning a racoon came around the corner and was crunching away in the baby pen feeder while i was standing right there..and I must be watering the whole forest because we fill one of those huge poultry founts and within 2 days its empty..
