My 6 chicks seem to be doing GREAT (knock on wood), they are a week old today and growing! One of them however, has dried poop on the side of her butt. I tried getting it out but I couldn't, I guess I was afraid to hurt the chick. Is there something I should do?? Also, I read that before you put them outside, you should gradually reduce the amount of Heat Lamp time. At what age do I start doing that? Thank you all!
