The shade should not reduce the hatching success because the eggs will receive some incident and reflected light. I am not sure the covering board will reduce the light to where the FA will not grow. Run a test with two egg ribbons one with covering, one without covering.
Tell us about the results of your perch YOY production this year. How big are the ones that trained to eat pellet food?.
