Hello everyone.  I have a question...if I put ivermectin on the backs of my girls for lice/mites is there still an egg withdrawal time?  I think one of my girls might have feather mites as most of her back is bare even though she has been wearing an apron for over a month and it has gotten worse since I put it on her. 
		
		
	
	
		
	 I haven't seen any little critters, but I can't believe the rooster could cause all this feather damage/loss with an apron on her.  I know there is a withdrawal time if used internally for worms, just wasn't sure about the external application.  Any thoughts?
