I've noticed today, that there is a fluid filled blister, just above the right wing near the neck of my maran chick, what the heck is it, is it life threatening and will it affect my other chicks who are going into the brooder, help!
There are airsacs in that general area that sometimes inflate under the skin. Fluid filled + airsac (if it is) would be bad. But since you say blister, hopefully that is not the case...
