I use the same and haven't had any problems other than scaly leg mites on one hen.  I did get some frontline spray on prescription from our poultry vet.  It is not licenced for hens but there are none similar that are licensed.  There is an egg withdrawal period and also a withdrawal period for meat birds, this should always be advised by the prescribing vet.  Prevention is always better so I now apply Vaseline to my hens legs monthly in a hope no more will get them.

About 8 years ago my vet gave me Panacur (for cattle) and a very small plunger to worm my chooks. there was enough in the plunger for the 3 chooks. However it was too hard to press the plunger gently and one chook got the lot! I was horrified! I was not advised to withdraw egg either. However, I know better now.
By the way the chook was fine, thankfully.

I sort of put my faith in vets but even before this panacur/ chicken incident I was questioning their insistence on using a flea and wormer mix every month.  Having done some research, it would seem it is not necessary to worm every month but every three months.  They use the scare tactic of 'lung worm' to get you to buy it when there are other wormers that will treat for all worms...plus you can get a blood test every two years to test for lung worm and then treat if necessary.  I don't like putting unnecessary drugs into my animals or the environment but it so hard to find reliable advice as the vets make their profits from the big drug companies.
Sorry....a bit off topic

Clearly profit is nore important to those vets than animal welfare! Disgraceful
