Forgive me, but I just had to chuckle when I read that. It was a friendly chuckle though, not an "at you" kind of chuckle. These little boogers aren't as fragile as they want us to think. They instinctively seek out warmth and the security of being "hidden" and instantly memorize where food and water can be found. Other than that their needs are simple, and I'm learning from all of this that they are better at knowing and finding what they need than we are in trying to second guess them. Mine have been living outside, and for the first week they were there the night time temps were in the 20s. They did just great. Last night I had reason to go out there so I looked in on them. At only 4 weeks old ( and with the temperature being in the low 40s) some of them weren't even near the cave - they were roosting on the roost in their pen, quite contentedly, I might add, and some were sleeping on top and others around it. Only the very little ones and a couple of the older ones were inside the cave under the heating pad.
I was just as paranoid as you the first batch of chicks I had, so it's pretty normal I think for the first time chicks. I drove myself and everyone around me crazy, as Lazy Gardener and Beekissed can attest! This time I just look in, make sure their food and water is filled, and that's about it. The rest of the time I can just sit on a stump out there and watch them explore, grow, and become chickens! It's the most relaxed feeling!
