Hi everyone, I recently purchased two jersey giant pullets from our local feed store. They seemed fine for the first three days, but after began sneezing and had "runny noses". I researched and got some antibiotics (Duramycin-10) and had them on it for 7 days after they seemed to be fine, so I took them off. We went out of town from thanksgiving and when we came home, they were back to being "sick". This time, one would just sit there with eyes shut, very lethargic, she would eat and drink a little but nothing good. So back on the Duramycin-10 we went. Well, here we are on day 9 and they are still sneezing and have runny noses. They are acting like pullets, eating and drinking normal etc. but one just has this smell about her...they don't have watery eyes or any other symptoms that seem to stand out besides sneezing, snot and smell. I am nervous it would be something far worse. I don't want to keep them on the Duramycin-10 longer than the bag says (7-14 days) but I am unsure what to do. We have also put VetRx on their noses at night (and the rest of the flock). They have been with our other girls so I guess it's too late for segregation... I failed on that aspect *sad face*. Any input would be helpful. Would injecting antibiotics be a better option? Thank you so much in advance.
