I was reading a post earlier today about when chicks start to fly and most posters were saying about 1 to 2 weeks. I was thinking since I have my chicks in a brooder about 3 feet high I can wait on a top. They are only two weeks old. I know it was not five min. later and one of my polish chicks was on a light at the top (not in use). I got it off then it got back on a bit later. Got it off again then watched for a bit and removed the light. I thought well I took care of that then I went to get a cup of coffee and looked over the darn thing was on the side of the brooder just looking around. Man they are fun.
