Our 6 hens are 6+ months old. They have always gone inside their coop to roost at dark. Last night I went out to close the coop door and one of my dogs suddenly goes into point stance and gives a low bark. I look around in the dark and see that at least a couple of the girls are on the roost bar out in their run. I get a flashlight and sure enough, all six sitting happy on the outside roost bar. I checked the run and inside the coop and couldnt find anything out of order. They seemed content so I reopened the coop door and left it open. I just got back in from the exact same scenario tonight. The only thing that has changed recently was that about 3 weeks ago i installed some LED lighting to offset the deminishing daylight. They are going in and out during the day and egg laying hasn't changed. Any ideas what these young ladies are up too? Any reason I should herd them into their coop? :/
