Concerning bumps on chickens neck

[Chickens4572]

Hello, I wanted to see if anyone on her knows what these strange bumps on my chicken are.
I went outside today to go check on her as usual and when I picked her up I noticed these weird large bumps on her neck and I’m really concerned. I’ve never seen these on any of my chickens before and I’m so confused on what they are. If someone could please help me figure out what these are and if they’re harmful I would be so appreciative

I have no idea, sorry!

Are they warm to the touch? If you touch one is the texture hard or squishy?

Do you have mosquito?

Or possible bee stings

If they just suddenly appeared, insect bites or stings could be a strong possibility. Is she scratching at them at all?

Could it be fowl pox from mosquitoes? What is your general location?
