Well I'm in the country so I suppose it was just a matter of time. Plus I got cocky. After a week in the same coop but separated by chicken wire I introduced some month old Cornish X and NH Reds to my established RIR flock. My RIR's are great about this by the way! Very little picking on the little ones, just a few brief episodes of chasing. Anyways, with everything so peachy I decided to let the little ones range a bit with the olders. Big mistake! They're still small enough where I guess they look so delicious and easy to everyone. By 6pm my dog was barking like crazy behind the coop and look who I found with a little Cornish X half-way down the hatch! He was a Texas Rat Snake I believe (a.k.a Chicken Snake). About five feet long. This is him in a five gallon bucket. Guess I just gotta keep everyone cooped up till they're big enough to not be so easy
