I plan to build a run to keep 4-5 hens in while I am not able to "supervise" them around my garden. How will they take to being allowed out of the run on some days but not on others? I don't want to create spoiled chickens who skwawk all the time to be let out - I'm trying to keep the neighbors happy. Thier run will be about 10' x 10', with a house about 6' x 8". Any hen psychologists out there who can offer me some advice?
