As stated, this is my first time using the incubator. One chick hatched at midnight Sunday, one hatched at 5:30am Sunday, and another at 2:30am Monday (today). Realistically, how long should I wait for the stragglers? How long can the newbies be left in the incubator with all the 'yuck' ? Does it breed bacteria for the ones that are/aren't hatched yet? I might add that these are our first eggs from our Rocks (Rachel, Riley, Roxanne, & Rosalie) & their Olive Egger rooster, Barney. We chose the incubator because we'd never tried it before, and because they've never set on their eggs. The incubator is fun but I'd certainly like to see them set on their own eggs. We've raised purchased chicks before (5 days old), but never hatched. If the eggs are fertile in the nest, how likely is it that one of the girls will set on them? No one seems to show much interest yet. Could it be because they are young (in their first year)? Any input would be appreciated!
