EcoGlow or Sweeterheater?

[Rebecky54]

I'm looking for something other than a heat lamp for my brooder box in the barn. I need something for 50 chicks, so looking at the EcoGlow 50 or a SweeterHeater. Any opinions on which is better? What size SweeterHeater would I need for 50 chicks?

Thanks,

Becky
