Nova, I know, I know. They suggested keeping old chickens and new chickens in two totally separate flocks.
They suggested that we give our chickens 16 hours of light a day when we want them to lay. And they suggest cutting that light back to 8 hours per day when we want them to moult. Or we can just follow the natural seasons of a natural moulting in the Autumn.
And they suggested that we keep our coops about 52 degrees ideally in the Winter and at least above freezing at all times. YEAH YEAH!!! I WAS SO HAPPY! SOMEONE AGREES WITH ME ABOUT HEATING THE COOP!
I just knew my chickens liked a bit of heat!
Takes the edge off surviving and they lay better.
Commerical operations (which we are not) keep chickens at the IDEAL temperature of 72 degrees year round. That is the ideal temperature for chickens according to M.S.U. That is where their bodies don't have to make any effort to heat or cool themselves so all their energy can go into making eggs!
6 months old to 2 years is the peak egg laying time - anything after that is a bonus.
