I have four females that I think are building or getting ready to lay. I witnessed one ovulation for sure and she had her prelay she'd right on schedule. Now I know about 30 days to wait. I am thinking I missed an ovulation on another girl because she has what feels like 7 big, almost chicken egg size, eggs I am feeling. Do they all have a prelay shed? She looks fat, so maybe this is ovulation, or could she be ready to drop? I know you can't really tell without seeing her in person, so I guess the question really is could she have not done a prelay shed and then lay eggs?
