The liquid one is much like our 125 ml bottle of Safeguard for Goats. @Yorkshire coop
How's your math? Which one is the least expensive per milligram?
Average weight of a 2015 pea is about 3kg (6.6 pounds). A 3kg bird will need 150 mg per day for five days, and some people repeat in 10 days.
Total 10% liquid needed for one average sized 2015 pea for five days
3 x 50 / 100 x 5 = 7.5 ml per bird (1.5 ml per bird per day for five days)
Total 18.75% paste needed for one average sized 2015 pea for five days
3 x 50 / 187.5 x 5 = 4 ml (0.8 ml per bird per day for five days)
Please check my math!
