I placed 4 fertile eggs under a broody silkie hen, which she took to with pleasure, and then second hen joined in. They have been tag teaming ever since and today all 4 hatched! My question is what will happen now? When can I expect them to emerge from the coop with the chicks? My second question is, I left a few of their own unfertilized eggs in with the bunch so they felt like they were sitting on the amount they wanted so should I remove them right away?
