So. I got the chicks moved to their new coop. They were so excited I couldn't even get a pic of them, they were too busy running about and scratching in the new shavings.
As I finished up with them, Olive was walking by. So I snatched her up and gave her a DE bath. She was a good girl. I just love her. She has the dust-bunny-looking groupings at the base of her feathers around her vent.
Then I decided to go ahead and wrangle the other three since they were headed to roost. I learned some things during all this:
1) Sweet Pea, the "other" Black star, doesn't care for being caught but was quite sweet once she realized a free massage was involved. She didn't really have any obvious signs of the crawly critters, at least around the vent, but got a good dousing anyway.
2) my BO has actually turned out to be impressively meaty, and will probably end up on the table one day after serving her laying purposes. She is a *beautiful* girl too! She also tolerated her DE bath well enough. Oh, she was also the WORST infested bird, but what I saw on her was the big RED mites, ALL around her vent.

Ugh. Anyway, apparently they've not caused her any harm as of yet as she certainly isn't poor by any means.
3) My red star was apparently a velociraptor in her previous life. Luckily, in MY previous life, I was a highly-skilled velociraptor wrangler, subduing said birds with two hands while using my third and fourth hands to apply velociraptor stuff onto their hineys. She was ****** at me!!
Anyway, how long until I look for results? Them repeat in two weeks? Right?
