Raccoons are the pits.  I also think it looks a bit like coon scat.   Sorry about your loss!
My neighbor’s entire flock was wiped out over 2 nights from raccoons.  So, 2 neighbors and myself have set traps and caught and killed 9 coons over about 5 nights.  According to others in the general area - there is a high population of raccoons this year, so more problems.   You are further East, but might be same issue for you, a high population of coons.  
Live traps and a .22 are a good combo.  The .22 will nearly sound like a pop if anyone e is close enough to hear it.    There are other traps you can set, some are kill traps (Conibear) but Can also kill cats/dogs if they roam at night.  Some are dog/cat proof like a Z-trap.   FWIW, coons like marshmallow, but cats don’t.   Peanut butter, dry or wet cat food, canned sardines.  Canned food can just have the lid popped but not removed -the smell will draw them in.   
Relocating an animal to ANY land That is not yours (including public land) without permission is usually illegal.  So, if you do not want to kill the raccoons, then beef up coop and run security.  
Good luck!
