I COPIED THIS FROM A PM FROM DAVID_THE VET I cannot enter a reply through the forum, not sure why apparently the topic does not exist! Anyway too much Emtryl can result in the same signs as the nervous form of paramyxovirus - twisty heads etc. If you have not given too much then plain water will help them recover. If too much for too long and they die. Relatively easy to overdose - e.g. they drink more when feeding youngsters and in hot weather. should not be a problem now. Allow 50ml per pigeon per day. If they drink all of the medicated water then just fill up with plain water for the rest of the day. best wishes, David
