I have a flock of 9 laying hens. All are healthy as can be. 2 of my girls are Australorps and usually give me a steady 2 eggs daily. So, for the past 3 months I've had NO eggs. They are on the same food as always, same water, same coop, etc. The only thing I can put my finger on is that I did have a snake show up about 3.5 months ago or so, but the chickens acted like he wasn't there and continued to lay. About 2 weeks after that was when I quit getting eggs. Also, I noticed a lot of feathers in their pen and original assumed they were all molting ... but does it make sense for ALL hens to quit laying and for this long of a time? Any advise for me?
