I left eggs in the coop this week on Monday hoping to encourage a hen to sit on them. One of my BA's started sitting yesterday (Tues) afternoon around 5-6pm. She was still on them at 9:45pm. I went out at 7 this morning and she was on the roost. It is now 3:30 and the eggs are still out there. Are they okay to eat? Does anyone think she may try again? Should I swap out the eggs for fresh ones? Any advice would be appreciated!
