what predator is killing my birds?

[Chicks in VA]

so long story short my chickens are in poultry net and one got taken by a ground predator. There is a 50 yard feather trail plus 2 piles of feathers and bones right inside our Woodline, my guess is its the fox that killed my game bird a few weeks back? Also I'm thinking it may have been teaching its young to hunt due to the 50 yard feather trial , I found one pile of feathers and bone it had the ischium and a wing and nothing else (I'm guessing that's where they finished the bird off by eating it)

i will be setting some trail cameras out!

Thanks!
