my hen has been setting on eggs for approximatly 23 days. I know most of them are bad because I can hear them slosh when you shake them lightly. My ? is, can I put a new batch of eggs under her, I know my eggs are fertile because my roo is quite the busy fella. So does anyone know if a hen will set long enough to hatch a second set of eggs. I believe the problem began with the musical nesting with the other hens since I didn't isolate her. anyhow should I try a second round of eggs or will it be a waste of time. HHEELLLLLPPPP
