Got new goats as I posted two days ago and now have started treatments and readying up their vaccine and whatnots. Yesterday gave their first Cydectin and will do 10 & 10 days. Today I started Cocci prevention. I did a three day mix then I’ll pour out balance, which want be much at all. Then I’ll do the two day mix for total of 5 days. My problem is now when I finish the 3 day mix and was putting the Corrid back in the plastic ziplock to put back in the refrigerator, I noticed the date of expiration of Aug 2017. It has been kept in its original bag ( small corner cut off) inside a ziplock bag, in the refrigerator. This August it will be 3 years old. I thinking maybe it’s still good? What do you think. I gave 1st dose today anyway.
