i think you mean pre lay shed. she probably hasn't ovy'd yet you can't miss it. I spent this whole season sure I was seeing it but it was just building. Sure enough i couldn't miss when i had the 4 ovy's i got this year. Watch close after that...
Eggs will be 44 days after ovy. Pre lay shed 16 days later, then eggs 27 days after prelay shed. Good luck and post pics.
