I would agree that a large sytem would be needed. A heading pad mama would work much nocer with this situation. Chicks are looking good. Is that a feather duster they are under.with solar a really large bank is needed to run a heat lamp kind of set up... I wonder if anyone of the grid is rearing little chicks and how. we did not get much yesterday compared to last week all melting fast. my waist high snow banks are all gone. all the massive melting puts a lot of stress on sumps so. that part is kind of scary... my little ones are all right and growing.
