Data, on my experiment, already.
Today is the first day of feeding old, what I would call out of date, Purina brand All Flock feed. (7 months old. Cringe.)
Today I got two eggs. So, what does this prove? (drumroll)
That sometime yesterday, hours before I even bought this feed, two hens ovulated. And I think that that is ALL it proves.
I'm not even certain which hens. It might not include the one who's been laying 2 out of 3 days, and today would have been day 2.
The other BIG thing that might be relevant is that today is the third day in a row that has had several hours of sunshine.
My money, if I were a betting person, would be on the sunshine.
