I have been ding search after search after search trying not to ask a question that has been answered but I am still a bit confused. I have seen so many different amounts going back to posts from 2010 on up. Is there a general senses as to how much per gal. Had a couple chicks show some signs of the Klingon attack so ran and got some I had to go into the organic section (first time ever) On a side note another on got poop on its neck My daughter cleaned it off and put it back. The rest went after that damp spot like piranha. Took it back out until it was dry. When we but it back again the others were like " hay Val where you been good to see you."
