Hi all. Wednesday I noticed my 6 month old golden comet had very watery diarrhea, and at one point it looked like there was a white foam in it. I kept an eye on her all day and she seemed fine (eating, drinking, very active) so I didn't think any more about it. Due to my work schedule yesterday I only got to observe them for an hour last evening before dark. I didn't notice anything unusual other than her crop didn't look as full as it usually does in the evening, but they didn't get out to free range because I wasn't home, so I thought maybe that was why. This morning when I let them out they all ran out to the pen, and the GC stopped and let out a gushing large amount of watery diarrhea. I checked the "poop chart" and it is most similar to a cross between clostridium perfringens and a hen not eating enough. I inspected it very well and did not see any worms. I alternate giving the girls oregano and supplemental silver to ward off anything infectious, so I don't see how it could be a virus or bacteria. Are there any worms that cannot be detected by eye? Yesterday she laid one of her famous gigantic double yolkers, so I don't think her diet is insufficient. (I think I feed my girls very well, and there is only 2 days out of the week they don't get to free range at all). Should I just ride it out and keep an eye on her or is there anything I should treat her for? I'm headed to the farm store in a bit so I can pick up meds or worm medicine if needed. Thanks P.S. All the other pullets are fine.
