Thanks for your knowledge. However, I am a clean freak when it comes to my chickens environment ....we must take this into consideration as a deworming preventative measure. If we keep our coops and free range area clean then this is a big preventive step towards healthy happy birds. 
		
		
	
	
 I have always used DE for my poultry. However, if a person is have a severe problem with infestation than by all means use the potent wormer. Your input or feelings about other chicken owners methods are defensive and discriminating. Would u like for me to attack your methods of caring for your chickens "Goat wormer is useless" . ....I don't think so my dear.
