Neighbour making formal noise complaint.

[Hen friend]

Hi, I used harkers spot on containing invermectin on my Serama. Just wondered how often I need to do this? I've done two drops about 4 days ago. Do i repeat in two weeks or every few months. Thanks

If you’ve never wormed your hen, you can repeat after 2 weeks, to prevent a second infection with the eggs that weren’t killed during the first treatment. 

Some worm every 3 months or every 6 months. But it might be better have a worm count done every so often to see if their is a worm burden to begin with. Vets can do this or get a worm count kit online and send it in the post.

Hi, they were one year old when I bought them so have been wormed before. The drops are more for lice.
