So i have a flock of six chicks, right around the nine week old range, i have built them a 4x6 coop with a 101/2 x 4 foot run and it seems every night since i have put them in the run they wait to long to return to their coop so the coop is dark. when i go and check on them and to close the door to the coop they are all cuddled up and sleeping right at the door and on the ramp. once i turn a light on for them that i ran with extension cord they all grab something to eat and some water and then eventually go up to the roosts. Does anyone have any idea that i could use to have some kind of solar powered light that i can hook up that will automatically turn on around dusk time frame and stay on for maybe an hour or two max just to give them time to come in, unwind, eat and get onto their roost. light does not have to be solar but i would like it to be automatic. thank you in advance.
