Do you really think that a bird thst lays 259-330 eggs a year (without any supplemental light) is natural?! The red jungle fowl lay 2 clutch of 15 egg each in average, a year. Everything beyond that is caused because humans manipulation . There is nothing natural in chickens! They are human manipulated laying machines.That coop is incredibly small for 6 hens, and I hope they are only in that at night to sleep. I know the box says it's made for xxx hens, but that really is incorrect, and it's a shame that the coop manufactureres get away with that kind of mass disinformation.
Anyway, this isn't really egg-laying time of year so you shouldn't try to force eggs out of them with artificial light unless you relish the thought of death by ovarian cancer. (I know you don't, that is just the consequence of excessive ovulation that kills the vast majority of all laying hens.)
It's good for them to NOT lay because laying eggs incessantly takes a huge toll on their bodies and eventually precipitates reproductive disease that kills them. You will wish they never laid at all when you're holding their little dying bodies in your arms and watching them gasp their last painful breaths in the final stages of ovarian cancer.
I give ALL YEAR LONG light and what I get?
1. Constant laying with pauses that the chicken fesyology and endocrinology decided.
2. Less stressed chickens
3. The most important thing is that my chickens have very very miled molth and in the SUMMER TIME and not in winter as the most of you do, there is no logic of loosing feathers at the time when chickens most need them!
