I have never used blu-kote. I think we need a sticky for basic wound care on here, I will ask my veterinarian (who is a chicken nut like us) for some assistance.
There is a lot of fancy stuff that is not needed, being recommended and some of it actually harmfull.
Saline solution is one of the simplest and safest products to use for cleaning wounds. Don't worry about stitches. Chickens heal very well on their own. I've had a chicken with it's butt chewed off recover completely. You can apply neosporin, but apparently there is a kind available with pain medication, that is not recommended.
Your chicken is probably in shock and putting all her energy into healing. Just keep her in a safe and warm place and let her rest.
Feed her extra protein to help her make new tissue.
