I am so confused. The last worming gel I used was very clear about dosage. The bottle I have says to dilute 1ml per 9 ml water and provide this as the sole source of water for 2 days. Does this mean I would use the whole 50ml bottle and mix it with 540ml of water?! That's like 2 cups of water for my 9 chickens?? The dose for giving it "by mouth" would work out to be about 2ml per bird as it says dilute it at the rate above and give at .5ml per 100g bird so a 2kg bird would be 2ml. I'm certain my birds need more than 2 cups of water for 2 days and if they drank it all that would be 50ml of gel consumed by 9 birds instead of 18ml of get if given by mouth? I CAN catch all my chickens and give by mouth but then I have to keep track of exactly who I have given it to and I have 4 kids under 8 and not a great back I'd much rather put it in their water!!
