Chicken skin under wing discoloration

[hnt15]

So I have been treating my chickens for a respiratory issue and today when I looked under one of my chickens wings her skin is a blue/green color...could this be bruising from the shot? I am using 20g needle...or is it something else I should be concerned about? I also noticed her snood looks a little whi in e instead of read.

Any information would be greatly appreciated

Discoloration is a bruising/reaction to the needle. Comb color is definitely off, but not certain what's going on there.

If you are using Tylan50, it can be given by mouth. Dosage is 0.3 ml per pound of weight twice a day for 5 days. That is some pale comb. I would look his vent area over for lice and mites.

I am giving Tylan50 by injection...no live or mites have also been rubbing Vetrx under their wings and on their beaks to help with the respiratory issue
