This is my leghorn who is about a year and a half old. I just noticed the blisters this morning. Other than the blisters she seems to be acting normal. She isn't eating her layer pellets as much as I would like but she will eat anything else we give her. One of her blisters is yellow and looks infected and the other is kinda clear and filled with liquid. I'm going to put pictures of them below. I have no idea what this could be or how to treat it. I thought that it might be fowl pox so I already separated her. I put iodine on her 2 blisters and wattles then I covered her comb and wattles in vasoline. Was this a good idea? Should I keep her separated? Should I keep treating her with iodine and vasoline? I still don't know what this is so please give me your opinion if you know. I want to know what it is and how to treat it. Any advice will be helpful and welcomed! Ps: we just had a big artic freeze last night. It's been around the 40s and 50s but last night it dropped to 15 degrees and the wind was blowing hard. She was inside the coop all night and was protected from the wind in there. Does this have to do with the drop in temperature?
