I have eight chicks (quail, if that matters) that are two and a half weeks old, feathered except for their heads and breasts. The plan was to move them to a grow-out pen inside the main outdoors enclosure to let them get to know the current flock. They'll have plenty of water and shade, but I'm a bit worried that the temperature jump from 73F inside to 100F outside will be too much of a shock for them. Should I take them on "field trips" outside first to get used to the heat, or could they be fine moving straight out?
