We have 5 white leghorns, all of which have continued to lay throughout the winter months. We don't use any artificial lighting but they do have the ability to come and go from the coop to the run as they please (it is completely enclosed) so there are mornings that they are already up, well before the sun...they soak up as much of the sun as they can it seems. Anyway, I had assumed that they would stop laying when the days got shorter and then for sure when the temps dropped into the teens/twenties as they have been for a few weeks now. But, they didn't. We are getting a few less eggs each week but overall there are still usually at least 3-4 eggs in the nesting box every afternoon when we collect. What I have noticed is that the quality of the eggs has decreased (thin shells mainly, which is causing more broken eggs in the boxes) and they seem to be smaller now. Is that a normal thing that happens during the winter? We don't use a heated waterer but we do replace frozen water with fresh water a couple times a day (although they seem to have fun pecking at the ice) and they always have a full feeder of Layena crumbles. I do supplement with kitchen scraps - mostly produce, occassionally carby things like slightly stale bread or the crusts off of my daughter's sandwhiches. About a month ago I did pick up some scratch and have been giving them a bit of that a couple times a week. Because of the drop in temps, I read that it was good to give them some of that to keep them busy and "fuel their furnace" - don't know if that is true or not. Anyway, I guess that is a really long post for a simple question - is it normal to see a decrease in egg quality during the winter months? Thanks in advance!
