Ok so I started a batch of chicken and duck eggs this last Monday. The chicken eggs are planned to hatch in 21 days total time, the ducks take 28. What do I do?? Do I remove the chicken eggs at day 21 to another hatching area? It's difficult with 2 different hatch dates because ive read that you have to stop the egg rotating machine 3 days before hatch. I'm Not sure how I'm Gonna do it.
