"Dump nesting" occurs
when a number of females lay eggs in a single house, which
sometimes results in clutches with over 70 eggs. A smaller nest box was designed and "dump
nesting" was reduced. Although fewer ducklings are fledged
from each box, the survival rate is improved and the cost per
fledgling is less. Our Small Hooded Merganser House comes with a wire ladder and nesting
chips, and the front opens for observation and cleaning. |
