I have 4 chickens. 3 RIR, 1 Buff Orp. 8 months old. I was getting 4 eggs/day, then 3, then 2 now today only 1. I see some normal poops, but more and more I'm seeing wet, orangish/brick (no blood, not overly red) splats that look like they have grainy texture. I've looked at all the poop pics and found nothing that it resembles. We have treated for Cocci (just in case) with Corid and for worms with Wazine 17 for 3 days so far. Cleaned coop, raked feeding area. They eat layer feed. We used to give them wild bird seed but got the idea that it had too much protein so stopped that a couple weeks ago. One girl stopped laying possibly 2 weeks ago, yesterday we got 2, today only one. They are all eating and drinking, the run is very large with grass, so they forage for bugs. None even look sick! Help!! Any ideas?
