Oh, no. They were screaming because of raccoons. One was traumatized enough to wake up every 30-40 minutes after the attack to start screaming again. I happen to have this neighbour's number, so I texted her when I first heard the screaming. I found out in the morning that she's out of town for the rest of the week.
I feel bad because one of her survivors seems to have gotten out of my yard. She's one of those tiny ones that looks like they're wearing a crazy wig. I looked for her but couldn't find her. Her silkie had me chasing her around the chicken yard for over an hour to get her cooped. The others were much more cooperative.
