Hey kdr2171, mine stopped laying a few months ago too. I have a lot of different types: turken, wyandotte, barred rocks, australorp, cochin, easter eggers, Sicilian buttercup, red sexlink, silkie x, etc and they all just quit.
Since I was still obviously paying for all that feed, I didn't want to be also having to buy eggs (store-bought eggs...
). I tired adding a light, but I didn't have a timer yet, just turned it off and on when I could remember to do so. Predictably, it didn't induce any egg-laying, just a coop-wide molt. Sigh.
I got the light on a timer and two more weeks passed with just one brave bird laying daily. I added hot mash in the morning with meat and veggies mixed in. Two days later, I went from one egg to 4. It's been a week and I've been giving hot mash each day and I'm up to 5 eggs a day.
Maybe try that!
