My little chicks were moved into the coop last Saturday, I had to order some non-slip tape to put on the ladder because they were having a hard time going up and down. They have slept huddled up every night in the bottom of the pen. I finally lured 4 of the six into the closed area and locked them up overnight. I installed solar lights in the coop so they could have light all night. Last night I looked out and all were up in the enclosed area! My question is, do I need to shut the door in the summer time? It's extremely hot here in Louisiana and there is a window with the hardware cloth that is open all night. I have installed a solar electric fence around the bottom of the coop and hardware cloth is buried all around the bottom...any advice is welcome!!! I'm a newbie!
