Hello there - I added to my flock of hens this summer. I have 8 hens that are one year old and were very good layers. My new chicks didn't seem to bother the original crew as far as egg production or weird behaviors. But all of a sudden, the girls have all stopped laying. Their feathers looked ruffled. Also, Their poo looked and smelled funny so I had my vet check it. They were full of worms and coccidia. The vet said that would hurt production for sure. I dewormed them and treated their coccidia. At my vets recommendation, I treated the coccidia by using medicated chick starter for 10 days. Has anyone ever had their entire flock stop laying because of this? How long until they start laying again? Could I be dealing with something else more sinister as far as disease goes? Any and all advise is greatly appreciated.
