Help! I have 11 pullets (16 wks old) that I put in the chicken house with my other hens. They have been in the chicken house 6 wks and refuse to leave. There is a short tunnel that goes from the house to the run, and we open the run every day to let the big hens out to free range. I have tried making a trail of scratch grains through the tunnel and the run to the door of the run. No luck. The pullets go crazy when the big chickens are in the chicken house. I have raised chickens for 15 years and have never had an issue like this. I may try catching them and putting them outside for a day without letting the adult birds out. Any ideas?
