Chicky pillow is finally incubating a nest of eggs! she started with 10, but our other 2 hens keep depositing eggs near her and she takes them in - she has 18 now. I marked them all, but this is not fail safe - today i broke 3 good eggs for cooking- not a pretty sight - so i'm leaving her clutch well alone now. Trouble is she will have eggs of differing ages. Do i just wait for the first to hatch and assume the rest are going to be abandoned? Can she possible go on adding eggs. i went out tonight and candled a few - some showed very little, another was completely black - does that mean its nearly ready or completely rotten (another fear) aany advise would be appreciated.
