Wazine only kills roundworms from what I understand.. it is used for, but not recommended for Laying hens... Search for the withdrawal period if you choose to use Wazine... and know that chickens get many types of worms and Wazine will never treat all of them.
How old is the chicken/the flock you suspect of having worms? I don't use Wazine.. the warning not to give it to egg producing chickens, period.... and the fact that it does not kill all worms.. I just think there are better, safer, more effective choices, my own opinion.
Do Search "worming"... and do look to and trust posts by dawg53 on worming..
I would not redose with Wazine.. I would wait the ten days ( It's ten days with other wormers, so maybe the same with Wazine )... and then I would give a different, more effective wormer that kills all types of worms.. such as Valbazen?
Search "Worming with Valbazen".. "Giving medications orally", or "giving oral medications".. "Valbazen dosages".. "Worming"... etc... and do seek out posts by dawg53 on worming for best info.
Good luck.
