I have a friend that I met on this site and she was given some Silkie chicks (varying ages). She already had some Silkies and unfortunately the new additions have lice and so now hers have lice as well. What is the best treatment for chicks like 2 weeks and older. Sevin or a drop of Ivermectin on the shoulders or what? And the reason she knows the new chickens had lice is she has gotten chickens from her before and the same thing has happened and she had to treat all of hers as well.
thanks in advance
