Stayed out in the building for a few hours last night and nothing. When we gave up, we put CeeCee our labxmalamute mix outside for the night. I'm sure whatever it is will be back so plan on trying again tonight. This was entirely my fault. Due to a broody in the coop and the bigger girls bothering her in the mornings if they are not let out at sunrise I was leaving the coop doors open at night for convenience. That has changed and back to being locked up and unhappy girls for a hour until we get out there in the morning. If this takes a few days to figure out what it is, I want to tie CeeCee up beside the coop with a chain long enough so she can get into the building to sleep. Problem with that is CeeCee is a 99% inside dog. If it is a coyote I also do not want her tied up incase it tries to fight her. CeeCee is big, 120lbs of muscle, but if it is more then 1 coyote she would loose that fight.
