40 degrees during day and 30 degree at night with temps climbing in the later part of the week. If I place the heat lamp in a Waring 2 X 3 coop with attached draft panels and bed the old nesting box then tarp it after sundown do you believe the heat will be enough??? 3 feathered banties (big bird feathers in) I feel bad for the birds because they are in a large dog box in my kitchen. hope to hear replies soon.
