Weather Opinion

[Tail Feathers]

Lovett Williams wrote about a cold snap in Florida in the low 30s after nesting had started he says the hens stayed on the nest and the eggs survived the cold. If photo period was the sole determining factor the breeding/gobbling/ nesting dates would be more defined instead of an approximation from year to year.

I'm pretty sure it was Lovett Williams who wrote what I kind of paraphrased earlier.

There were birds gobbling on my SonIL's farm in January, coldest one we have had in N Fl in ages.

Photoperiod absolutely affects breeding season in some species (such as the turkey).  As does weather.  They are not mutually exclusive, one or the other.  There is even evidence that other hormones are involved besides just the typical ones from mammals.  It is interesting, but nothing I ever really studied much.

I gotta be there start to finish so doesn't really matter to me.
