Lice:(

[Chickenlover35]

I think my chickens have not a bad case but a substantial amount of live within the flock! What can be done...?

If you meant lice, I use ivermectrin 1% and pull up some with syringe then shoot it into small diposible container and take a eyedropper to put drops on them about 6 to 7 drops for large fowl right down on the skin under the feathers between the shoulders behind the neck. It will also worm them too.
I treat mine 2 times a year, first of spring then again in fall. But with this weather I actually treated them again last month.
