Well I locked em this evening. Plan to let em out each AM. The run is predatorproof as I lost all 23 birds that were in that facility-run/scared to death by something that tried to get but couldn't. The one thing I have noticed is that the 7 hens and roo that do go to roost all congregate at the bar ends near the ramp/ladder-sorta seems like they are blocking the others but I have the same setup in the other house and no trouble over there. ??? Perhaps I should post a pic of the setup.
