I have 14 two week old chicks in a brooder that is about 8 square feet in size. They are growing fast and seem comfortable for now, but I am beginning to think that they will be too big for the space very soon. I am building an 80 square foot coop and it should be finished this week. It is well insulated but I am worried about moving the chicks from the warmth of the brooder into the coop because the nights here in North Carolina can be very cool. What is the best way to make the transition into a larger space. I don't want to shock them with temperature differences. If I hang the two 150 watt red lights in a corner with lots of bedding material will they regulate their own temperatures by moving closer or further away from the lights. These are my first chicks so this is a big move for them and me. I am enjoying them but for the life of me I don't see how anyone can name baby chicks and know who is who. Thanks.
