My babies grew way faster than their chicky companions and are now double their size. They accidentally hurt the chicks now when I give new water and food. They're just so big and excited. I want them out and in a plastic brooder (because of the water). I down know how much longer the plastic liner I've taped down will last! They sleep really far away from the light any more. The heat has been 84 outside (they are in the unheated/cooled shop) I don't know how cold it gets at night, maybe 60s. I don't want to buy another light since that helps me make sure I don't have to many babies at a time. They are 2.5 weeks old.
