Hi guys, I need some help! For the past two months I've been battling with lice on my hens. Once a week when i clean the hen house (I poo pick throughout the week) I've been adding lice powder to the house and dusting the whole flock as well (under wings, around the vent - wherever I can see lice) The number of lice has declined but I can still see them and baby lice too - they are definitely not overrun, I can only see a few on the individual birds but I don't know what else to do? I've attached a photo of the products I've been using (and I've sprayed the house with nettex de-mite spray as well) The birds Look much healthier than when I first started. Is this as good as it will get or is there a way to get rid of them completely? Anyhelp would be amazing!
