My chicken coop has an area underneath it for a run, with an entrance/exit to the non-coop run. For some reason I can't seem to be able to get my chickens into that area. It has a ramp down with a trap door that covers up the entrance, but that trap door is always open. This is starting to be a problem because I am not sure my chickens are getting the needed exercise and extra nutrition (bugs and other forgeables), as well as making it very difficult to clean the coop.
I have had my chickens for six days, and they were not hand-raised (they are four/fiveish months old) so I am also working on getting them comfortable around me. What can I do to get them to go down there? I have tried putting treats (mealworms, watermelon, and scratch) around the trap door, on the ramp, and in the run but they don't seem to go after it. A chicken has fallen/been pushed down into the run three times but they always try to get out really fast and do go off of the ramp. What should I do? Is this not issue?
