So I let my babies go outside to play in the grass today for the first time. They were out for a couple of hours, and I kept an eye on them the whole time. They seemed happy and comfortable, and they had their food and water dishes with them. Since I brought them back in, though, they have done absolutely nothing but sleep. I've seen them get up here and there to eat or drink, but otherwise they are sacked out. It's been about 5 hours since they came back in. Did I harm them by letting them be outside too soon (they're about 2 weeks tomorrow) or do you think they're just plain exhausted and they'll be fine once they've rested? It was a big day for them. 12 are male Cornish Cross (which I've noticed tend to be lazy butts anyway) and 3 are female Barred Rocks.
