I did not find Blue-Kote this morning, but did find Blue Lotion that seems to be very similar but comes in a bottle with a dobber instead of a spray. Has the dark methylene blue dye that masks the wound color very well. I liked that the bottle came with a dobber that made it easy to apply to the wound. Glad I wore gloves to apply it. That stuff would have stained my hands pretty bad!
The wound now looks a dark, dark blue/purple and seems to really not attract attention. Thanks for the suggestion. I think the chicks will be OK.
That sounds better than the spray anyway. Glad to hear it's working. Good luck!
