So I have a 3x5 coupe attached to a 5x7 aviary for my 20 quail. They are about 4 weeks old fully feathered and healthy. I open the door to the aviary and let them out in the open every afternoon. They all run outside and then refuse to go back in for the night. The huddle together after an hour like they are cold. Temps are in the 50s 40s. So I pick each guy up and put him back into the coup for the night. should I just let them be in the aviary all night.They can go into the coup whenever they want but they never do.
