I have 5 hens and 1 rooster. I added two of the hens about a month ago. Had been told they were laying. My other three continued to lay normally and the new ones began to lay now and then. However, their production has not been consistent and now someone (one of the new ones I am pretty sure) is laying on a roosting shelf and the shells are so thin they break before I can collect the eggs. And my original three hens are just laying sporatically. It is very very hot and humid here right now. Any thoughts?
