They are my first ever hatch of my own chicken mutts. Hmmm- maybe they ARE cold? They are 3 weeks old, and they are in the house. The thermometer says 70. Maybe I'll turn the heat lamp back on and see if it helps. I was hoping to kick them out is weekend. maybe they're not ready. Ugh...Lol, the only time mine did that was when they were cold. What do you have?
