I have digested so many worming threads here but I still need help. I de-worm my girls 2x a year, and I rotate between safeguard, and valbazen. I individually syringe each bird, with doses recc in threads here. Then repeat 10 days later. In July, I noticed some large round worms in poop, even though it wasn't time to worm the girls again. So, I gave them wazine, followed by safeguard. For wazine, I follow bottle dosing(give only source of h2o for a day w/ wazine dose). What I did not do is give them wazine 30 days later as the bottle suggests. I did, however, dose them with safeguard 10 days after their wazine dose. 3 months later, I find a roundworm in poop. So what gives? How should I be dosing to rid them of these round worms? I thought that wazine, followed by safeguard or valb, 10 days later was the answer. Should I wait longer for the second/final worming dose? Is there a chance that I just have wormy soil, so they may develop a load every 3 months? Help? I am going to dose these girls, again, tomorrow, and I really need to kill them this time. Thanks!
