I raise Silkie Bantams, which are known as layers.  They do not lay daily year round.  I live in the country.  My neighbors have chickens - leghorns and reds - and these hens take some time off in winter and late in summer too.  My lamb farmers raise layers for egg sale.  And they don't lay daily 365, either.  Perhaps feedlot birds are treated differently such that they feel the necessity to lay until they drop.  I would not be surprised.  It is also known that layers lay for 3 years and quit.  Mine are coming on 4 years and still lay.  But now that it's getting colder, they are not laying right now.  But this has been the case since the hens were old enough to start laying.

Anyone else here raise any of their own food?

But I am demonstrating from experience that domestic chickens don't lay every day of the year, which is what you claimed.  So there is no need to go further and compare with the wild birds to establish this particular fact... unless you don't believe me.
