I have 31 Texas A&M quail right now. I just got 26 of them today. Anyways, they are very yellow and greasy like they have been pooping on eachother. They were in a very small pen. I gently hosed them off a little and wiped them down with rags and they are still pretty dirty as opposed to my perfectly clean bright whit ones i already had. Will a dust bath clean them or do I need to do something more invasive than giving them play sand mixed with wood ashes? Thank you
