I made it thru the night and so did the chicks. They moved under the heat lamp after ti got dark but it took them awhile, they sat outside crying so I put each one in the warm area but they came out. So I went in and eventually they got it. I did put hardware cloth around the bottom part of the tractor today as I had dreams of coons gettign thru the chix wire. I'll sleep better tonight as will the chicks.
