Ok.....about a month ago I bought my own microscope and stuff to do my own fecals, but have been having a hard time figuring out what I was seeing.......well this week my new little guy got sick and had to take him into vet, while there they did a fecal on him.....came back with too many cocci to count, which is not good.....but I decided to use this situation to teach myself to do my own fecals, thinking that if there were to many cocci to count then I should be able to make them out really easy....so I did my own last night on him......Yes, I saw lots! So now I know what to look for as far as cocci......I did see 1 worm egg, which are much bigger.......so with this I ran fecals on my 2 older guys and to my amazement I found several cocci on their fecal as well, not as many as the little guy......my older ones just had a clean fecal done at the vets last week! So I am now treating all boys. I am assuming with our warm, rainy, humid weather we have had lately is probably making cooci worse and the fact that mine are on a grassy lot. I am a cleaning fool in my barn so I don't know what else I can do.....I also clean their water pails out 3x's a day. Oh, and my big guys are not in the same pen inside or outside with the little guys.
