Not sure what is going on with my pullets/hens. They are 10 months old. I was getting 16-18 eggs consistantly out of 21 birds daily until about 4 weeks ago. I am now getting 1-2 eggs daily. What can cause this to happen? The pen and coop have locks on them so I am confident that nobody is getting in and helping theirselves to the eggs. Is there some kind of predator that will eat that many eggs every single day for that long (haven't noticed any signs of predators) or would it more like be a nutitional need? I have a sencond pen of chickens who are the same age, fed the same food and I am consistantly getting 14-16 eggs daily from 21 birds. Any thoughts or suggestions would be appreciated.
