I have 14 - approx 5 week old chicks acquired from my daughter who was surprised with 20 babies one day coming out of her barn. She has about 40 chickens, 4 roosters that free range on 10 available acres during the day and coop up at night. I live in house on 5 acres adjacent to hers. Her chickens often visit my place. This is my first time owning my own flock. We plan to free range ours during the day as well. My chicks are close to fully feathered and are crowded in the brooder box which has been outside under my deck. I planned to transfer them to a chicken tractor today to keep them until we get a coop done. It is raining today and probably next several days with low's dipping to 66 ish. Is it ok to put them out on wet grass now? I stopped the heat lamp several days ago and low's have been 68-70. I look forward to learning from this group.
