So my coop is built under our patio deck, in the only place it can really work in our backyard. I'm quite proud of it as it is the 4th coop I've built and I applied many lessons learned from previous coops (Sand! Sand! Sand!). However, the one failing of the coop is that it gets no direct sunlight and even ambient light is quite dim. For perspective, on a cloudy day it is dim enough inside that you couldn't read a book comfortably. And we are here in the lovely and cloudy NW. I've used supplemental light in winter before here and am familiar with the good effects on egg laying, but my flock of three pretty ausrtralorps have decided to greatly reduce their laying here in summer. Now, I know moulting can be a cause of reduced laying, but my birds look pristine and there are no feathers laying around the coop. So my next theory is that they are simply not getting enough light (given that food and water are unchanged) Today I added a light to their coop and plan to have it on for about 12 hours a day. I want to do this for a week or two and see if we can get back to 2-3 eggs a day from the 1 every few days we get now. I'll post what happens. Just wondering if anyone else out there has a coop in a very dark place and needed supplemental daytime light to augment their laying, even before equinox.
