I want to add that I just found this thread and was thinking the same thing. My TSC, the chicks looked sick to me and didn't look very healthy. My TSC has now switched back to the oval tins on the floor and they look healthy now.TSC has installed new brooders this year that are severely abusive to the chicks. There have been several complaints on their facebook page and at their corporate level. Chicks are dying at a much higher rate due to these tower brooders. Please sign this petition to have TSC go back to doing what is best for the birds!

Thank you. Feel free to post anything you have seen regarding these bad brooder set ups. We went to Rural King yesterday and they still had open air brooders so this is just TSC handing over a project to an engineer to make the ideal brooder.
