Contaminated eggs

[RichmondHens]

I use Broadline on Greta (our cat) and she is always a bit off colour the next day, apparently frontline doesn't work on cats anymore.

My small animal vet told me that in some areas fleas are becoming resistant to Frontline and recommended I change my cats' flea control. I now use Advantage.
Using unlicensed spot ons on poultry is sheer laziness imo. It is perfectly possible to control/eradicate ectoparasites using other (safer) methods.
Right, I'm getting off my soapbox now .............
