Hi all! This is my first time raising baby chicks. We have 12 from TSC that my mom bought yesterday. She either didn't get the right answer or remembered wrongly, but she was under the assumption that they were around four weeks. Well, I google imaged it, and they look more like two week olds! Most of them are small, and the smallest have stubby wings. We do have three (Rhode Island Reds?) that are bigger in size, able to spread and flap their wings, so I'm not sure about their ages. I'm worried about keeping the temperature right. I peeked at the thermometer in the store, and it seemed to be at about 75. The temp in my brooder was mid 80's earlier, and right now it's hovering just under 90. I don't want to accidentally overheat them, but I don't want to chill them either! They seem to be split into two groups right now - one huddled closer to the lamp, and one huddled on the perimeter. All are eating and drinking and move around the cage peeping at times. Here are some pics so you can see their sizes! Its hard to tell but the one on the bottom is the biggest chick. He or she can fly a tiny bit inside the brooder. The very smallest, meanwhile, had a pasty butt when it first arrived, but we cleaned it and I've been keeping an eye on it! They are from Townline Hatchery in Michigan.
