This is too horrible! I have lost 3 chicks in the past 2 weeks. I searched the forum for this problem prior to posting but all the problems seemed to be related to egg laying; my babies are only 10 weeks old, not old enough to lay yet. We are in Texas and it is rediculously HOT! But my girls have plenty of fresh water, are in the shade and have a fan. I'm new to chickens and have no idea what this could possibly be. All responses will be greatly appreciated.
