so exciting!My own light Sussex, back up plan eggs are now on day 18 and I just locked them down...only five because like 6 weren't even fertile! I think she played hard to get with the boys. And a couple just stopped developing. They are due on Thursday so if they hatch on time, they will be exactly one week younger than the shipped egg chicks. So excited!
My last hatch went really bad... I put in 70 eggs and only 21 hatched. I don't know what the issue was.... maybe I should have de-wormed them prior to taking eggs... maybe some other issue... but the hatches before had no issue. So go figure! It could have been the coccidia flaring up... so many things could have gone wrong.
I envy you for being able to breed when you feel like it.
