Well my wyandotte hens have not laid a single egg in Winter - ever! and I am 68 so it must be an age gender thing...
Cant really see what the fellas age has got to do with anything.......
My wyandotte lay through winter and it gets real cold here. Wyandotte are a cold hardy breed that is why they have a rose comb. I think that the reference to age was ' tongue in cheek ' and more of an ' old wives tale ' thing.
