I recently went and picked up 3 baby silkie chicks from a local breeder that is NPIP certified and didn't bother checking them out before introducing them to my other baby chicks. Come to find out they had poultry lice I haven't seen any on the other chicks but they are different breeds and fluffier so I may just not be seeing them. On the silkies it's easier with their black skin. I've treated once with 'Y-TEX Gardstar Garden & Poultry Dust'. The instructions say to treat once a week. I guess I'm wondering if there is anything else better recommended for bay chicks ages +2-4 weeks, or if I can treat with this product more than once a week. I want to get this under control before I introduce them to their outdoor coop. This is my first go at chickens and I jut want to make sure I'm approaching this correctly....I don't think they have mites but I guess I'd like to use a treat all, with it being too toxic. Any and all help appreciated.
