I have eight 14 week old "chicks" that I have been attempt to to coop train for the last two weeks. Yesterday was their first time outside of the coop (in the run) and at dusk I went out to find them huddled under the coop; not inside I think they may be afraid of the steps going up, but how do I teach them that's where home is? I thought locking them in for a week and a half would do it :/
