Castport,
I am not trying to pick a fight either but I will say this with experience with my birds. I have 38 peafowl and about 30 other birds in the pen in the yard. Chasing and catching and forcing things down a peas throat is very very stressful to the birds. Why put them through all that when you can mix it with water and they drink it? I would have to catch 60 plus birds to worm them or I just put it in the water cause they will drink it. So far my birds must have drank enough cause they have no critters crawling inside them. I understand your bird vet told you to do it your way but ask your vet what he/she would do with 60 plus birds. What do the bigger breeders do - catch 300 plus birds? Would your vet catch each one or put it in the water? Why go to the extreme when there is no need. I had someone come in my yard and throw a sick rooster into my pen about a month ago. Now my pen has a padlock on it. Well I had my first case of blackhead, never had it before. I took a fish zole pill and let the peacock eat it. Blackhead was gone in a few days. One pill, one time, no catching, no stress and a very happy bird. I then opened my breeding pen and let that peacock into the pen to seperate him from the rest so I could treat the entire flock of birds cause if one has it then there are others who do to. I mixed 3 fish zole tablets into each gallon waterer and served it for 4 days. No more blackhead.
