I have just bought pure sulfur in the powder form. I'm thinking of dusting the hens for mites with it but wasn't sure if this was to harsh to put on them. So what can I use to weaken the concentration of the sulfur/ to dilute it. I was thinking just flour? The reason I am doing this is because in the local dusting material that costs 4 times more than a kg of sulfur basically consists of sulfur and 1 other material ( I will find the other one out in a sec ). So I am just trying to save a shed load of cash. Any help is much appreciated thanks in advance.
