So we rescued 10 hens from an awful situation and all are fine but our Penny, Penny's back is bare and down around her bottom- none of the others are like this but her- since it's bare the other hens are picking on her- we have sprayed her with blue kote to cover the exposed skin but there is not one particular bully in the group they all peck at her on occasion- are we doing the right thing here or is it possible she has lice? still new at this could use some advice! thanks to all!
