Hi all thanks for the input but we realized what the issue was.
With the sun setting a bit earlier and their coop in a different spot, was moved a bit in the expansion - my bad, so they couldn't find their way inside. Last night we put a light on they went all in and then we shut it worked...
Thanks for the info, we actually thought the same with our rooster, Martin is very protective and helpful. Will round everyone up when its time to come in from wondering the pastures and watches my every move with the chicks.
We are in South Carolina but can have some freezing temperatures in...
Okay so looking for reasons to their craziness or help.
I have 3 older pullets and Martin who always slept in their coop with no issues.
We do now have 6 - 6 week old chicks who we have recently divided off a section of our run (its huge we expanded for them) so that they can all get used to...
