My silkie hen is sitting on two eggs right now (one from yesterday morning and one from today), will that mean the potential chicks will hatch 2 days apart? Should I give her a 3rd one tomorrow morning? Would that mean a potential hatching over 3 days? I need to move mom & babies out of the nesting box as soon as they're born so it's a concern, need to plan this out... ps: one egg is small and one is normal -sized, is this an issue? THANK YOU!
