My hen has a little lump nodule thingy at the base of her tail it LOOKS like the hard casing of a feather but it feels like skin so I don't think it's a feather. When she cleans herself she seems to kind of scratch around it, shes not biting it hard but it's like shes itching it. (It's above her vent) Does anyone know what this is? Should I be worried?
 
	
		
			
		
		
	
				
			 
	 
 
		 
 
		 
	 
 
		 
	 
 
		 somehow never noticed this on a chicken before and then saw one when my broody hen was grooming herself - obvious concern was that bc she's been sitting for so long that smth had gotten infected but nope! Just the oil gland
