My female laid eggs 3 weeks ago. mom and dad are sitting on them. when do they hatch? i was told it should have happened already. will they sit on the eggs until i get rid of them or should i leave them alone? Thanks---first time grampa
Incubation usually lasts 18-21 days with cocks sitting during the day and hens at night. Incubation only starts when the last egg is laid so you should allow 7-10 days after your projected hatch date for any "late bloomers".
It really depends on whether the birds feel like starting another round - most likely they will. I would remove the eggs after time because if they start laying again you won't be able to tell the old eggs from the freshly laid ones and the older eggs will go "off". If an "off" egg breaks that is one of the worst smells around.
