I loved using Pam for follow up treatments every second night simply because its so easy and only ever did the one (heavy) treatment with nustock. I seem to recall it taking a long time to be able to see the difference as the old damaged scales stay in place for so long. Have you noticed any improvement or have they gotten worse?
So if you use Pam, would it be more beneficial to the hens to try and find the Coconut Oil Pam?
That's an awesome vid.
I think I wanna go with the one that inspired Geoff tho.

Also credit should go to Karl a Hammer of Vermont Compost, who uses flocks to work their piles. I posted a video awhile back of Geoff interviewing Karl, who started in the 60's. I personally do not like the seeming large "Buy a video" that Geof uses. Most Permaculture principles involve sharing skill sets to spread the word. Some hold workshops to build a rocket stove for example, but build it in someone's home, that is a win-win for everyone involved. Less knowledgeable individuals get taught how to do and the people that teach them get a stove built. That is just my opinion and view.
