Hoping for some advice - I have 10 barred rock and RIR chicks that are 6 weeks old. Last night was their first full night in their new coop except no one actually went into the coop! All 10 stayed out in their enclosed run. It's predator proof and there is no flap or cover over the door between the run and the coop. I think they may have been afraid of the gangplank as none of them will walk up or down it yet. My question is: how do I get them in to sleep at night? Do I even need to or will they eventually figure it out? Thanks in advance.
