So before I ask my questions, I want to give a little info. I have 10 barred rocks age 3.5 weeks, 5 SL wyandottes age 1 weekish, and 6 cornish rocks age 1 weekish. They’re all in the same pen together. This is my current pen that I am keeping them in. They were in a small pack and play and I knew it was too small so I rigged this up in hopes that there would be more room for them. My first question, is two lights going to be enough warmth for them? I have a third clamp light with a 100w incandescent light that I was using in the house with the pack and play. I also plan to close my garage door and possibly run a little space heater. My second question is that should I be concerned over chicken sneezes?? Their food is really dusty and I can’t tell if it’s because of the food or if they’re getting sick. They’re all still actively running about, eating, and drinking.
