Need to know how well your hens are producing eggs? Maybe you have very little room for seperate pens and have to keep many hens in the same pen, while still needing to know which hen laid which egg. With these plans this will be easy. Each hen will enter the nest and lay their eggs. They will then be trapped in the nest and will not be able to escape. This method should only be used for people that can be there to release the hens after they lay.
