I got some new chickens a few months ago and they are about a year and a half old. We set up clean nests and waited a few weeks. After a few weeks, still no eggs. I then bought some white ping pong balls and added them to the nests and waited to see if that would encourage them to start laying again. I waited and waited and here we are months later, and still no eggs.Their previous owners said they laid everyday over at their house. We feed them a good amount of food that's nutritious and they free range all day. We have other chickens but they are too young to lay so we have had absolutely no eggs in our nests. Why aren't they laying? Do we need more nesting boxes. We have 18 hens but half of them are too young to lay yet so we will add more once they are a little older. We have 3 nests at the moment. We have never had so many chickens. I am not sure what the issue is. What do I do?
