Worming chickens isn’t a terribly exciting topic I grant you but it is essential non the less.
There are various types of wormer products on the market from herbal to prescription only from a vet.
Through experience, I would personally recommend using one prescribed by a vet. This is because our hens picked up Gape worm (yes Gape not Tape) and the herbal product we were regularly using didn’t prevent or cure it. Gape worm is a serious problem and will kill the hen if left untreated.
Worming is especially important if your girls are static in an enclosure and not free ranging as the worm infestation will build up in the soil.
The down side to some prescribed products is that you may not be able to eat the eggs for the few days during the worming process. However it does mean your hens will be safe and healthy so please don’t neglect regular worming as it essential for the health of your birds.
We personally use Flubenvet and found it to be very effective:
