I have a 1st time brooder full of a little over week old chicks. It has been chillier than I would like it to be to take any field trips outdoors (which maybe its too early anyway) so I brought a few sticks, few leaves, and a rock in with a small amount of dirt today. Is that a bad idea/too early? Figured to start getting them outdoor exposure since if they were with mom they would be exposed anyway. Just curious on thoughts!
