I have 5 chicks 10 weeks old. Been out in the coop 5 weeks. The lowest on the order strggles every night to find her way to the roost. I provide a light shining on the roosts and dont shut off until all are well settled. My little one seems to have sight issues, she is the last to come down in the morning, and seems to struggle to find her way both at dawn and dusk while the others done seem to have an issue. Many nights she end up alone on the rafters near the ceiling. Most nights I have succesfully guided her to the roost with a flash light. Tonight I cant seem to guide her down and she is right up against the vent. If I open the front door of the coop ( see my home page) it is wide open and they flip out, so I cant open it and physically move her. Do you think there is a real danger in leaving her there tonight? Our temps get below freezing. Tomorrow our plan is to put something up there so she cant settle in in this space... any suggestions?
