Okay so I built a little pen in front of the door of the coop. I had to shoo the chicks out. They acted like they didn't want to come out of their comfort zone of being inside the coop to go outside. Then I closed the door of the coop where they couldn't go back in and they didn't like that but they got over it. Then I opened the door to go inside and out and I haven't seen them come out of the coop by theirself yet. I guess it's just they aren't ready and they don't wanna come out of their comfort zone. Oh yeah, it's almost 80 degrees outside and the sun is very warm.
