I just snook in the coop while they were sleeping and gently moved her long enough to dump a ton of fresh bedding on her nest to make it deeper/cleaner and put the eggs back and her on top of them. They are all still warm and I checked the one fertile egg I gave her and its still doing well. Should I leave it with her or take it back and put it in with the remaining 3 eggs that are developing? I doubt she'd even notice. You said your silkies only hatched 50% on their first time hatching? That makes me nervous. Although how many were they sitting on? I was thinking of leaving her with just this one or giving her all 4 developing eggs and take away the 2 infertile ones. I want to trust her since nature is suppose to be better then any incubator, i just dont know how reliable she is since this is her first time, but so far she seems like she's doing her job because that egg is still alive. If I give her these 4 then I could set more eggs instead of waiting but I only want to do whatever is going to give these 4 the best chance at hatching. Not sure what I should do.That's a hard choice. In my experience with my Silkies they usually only have a 50% or less hatch rate on their first clutch of 100 % fertile eggs. I would just keep doing what you are doing and don't change your plans due to the fertility of the eggs. You could always hive her the new chicks right as they hatch and start with a new bunch of eggs in your incubator.
