for those of you who are worried about dusting (yourself as much as your chickens) I read a cool tip today. Place proper amount of poultry dust (my prozap dust is about 1 ounce for 6 chickens so I divided one ounce into 6 equal parts. Think Scarface and illegal lines...LOL. I think I might also attempt to measure it as in tablespoons etc for future reference) place chicken in garbage bag with it's head OUTSIDE of the bag and rotate and gently shake the bag to completely cover bird with dust. Wearing of a mask is still advisable. I have yet to attempt this trick but it sounds encouraging. I have breathing problems so have delayed dusting. In the future I will probably go with some type of spray. I do have the advantage product for kittens that I have also considered using. Not sure what ppl use, kitten or dog application - they are different.
