I am fairly new to backyard chicken raising though I came from an Illinois farm where we had thousands of them, mostly leghorns. Here is my question/problem; I now have 2 RIR and 2 black sex link. A few weeks ago they got coccidiosis which I treated with Corid which worked great and they look very healthy. I now get 2 eggs per day and it appears it is the 2 black sex links laying and no RIR. Anybody have any ideas? I have even threatened the 2 RIR with chicken noodle soup but they just stare at me and talk
