We have a 7 month old Welsummer hen who appears to be scared to leave the roost. For a couple of months, she has paced back and forth and eventually flys down-usually crashing into something. If it is too high for her, I don't understand why she keeps getting back up there instead of perching on one of the lower roosts with the bantams. The past couple of weeks, every time I go check, she is still up there no matter what time of day it is. I am assuming that she is coming down and getting back up...SURELY she is leaving for food. She is a very gentle hen. The roosts are too high for me to get her. I stretch my hands way up there to feed her some bread and she DEVOURS it. Is this chicken ill or something?
