I have 1 cochin bantam that has been sneezing a little, has rattling and has a little bit of a runny nose (very little now) She's eating, drinking and being herself. Since she is in with my others i gave them all drumyicin today. I'm waiting to receive my tylan order which i should have wends. Ok to stop giving them the durmyicin until i receive the tylan or should i continue until i get it? Egg withdrawal for 1 day of durmyicin? Okay to move over from durmyicin to tylan right away? Any help would be great!
