I have 4 hens sitting now I don't need more chicks but two are right at day 22 so I am waiting for them to hatch. The other two are about a week and a half into it. I would like to remove all the eggs when the first chicks hatch. 1. Is this a problem? 2. How much longer do I wait for the first 2 clutches to hatch? Thank you for any feed back!
