I have a flock of ten hens that I treated for coccidiosis when they were roughly ten-eleven weeks old. I treated them for two days, waited a week, and then treated them for an additional two days as was recommended, and then I gave them a couple days’ worth of nutridrench after treatment with Corid. They looked and acted healthier, had vibrant feathers and ate and drank normally. Now they are well past the age where they should have begun laying eggs, and not a single one of them has laid an egg. They all look and act perfectly healthy. Good appetites, vocal, and interactive. They should have started laying over a month ago. Did I mess them up somehow with the Corid and nutridrench? Is there anything I can do to spur egg production? I have other hens that are laying normally so I know it isn’t the diet they’re on. And the ten non-laying hens were part of a flock of twenty that I split with a friend and hers are all laying now. Where did I go wrong, and can I fix it?
