Remove eggs as they are laid and replace with plastic eggs.
When all eggs are laid, replace the plastic fake eggs with their real eggs.
Now the eggs will incubate beginning the same day.
Hatching will be closer together and prevent losses from late hatchlings. Stop Over Producing
For Birds that won't stop laying
Replace real eggs with fake eggs and toss real eggs
Birds will be happy sitting tight and incubating
You have a couple of weeks with no production:)
