After years of wanting chickens we finally made the decision to get some a couple of days ago. We have 4 chicks: 1 Ameraucana, 1 Brown Leghorn, 1 Delaware and 1 Black sex-link The thermometer stopped working the first day so I have adjusted the heat to where the chicks seem happiest, going on their behavior. I know it was around 90 degrees while it was working though. I guess my main question is that one chick, the Ameraucana, seems a little quieter than the others. She eats, drinks, eats scratch from my hand if I offer it to her, but she just seems a little quieter and a bit less active. I've found a few little piles of loose poop, not sure who they are from though. Thank you so much for any advice!! Also is there a good reference book that would have specific information on raising chicks?
