Feather picked pullet with shrunken comb

[JenniferCNY]

I just went out to check on my 8 10 month old pullets (3 Barred Rocks, 3 EEs, 2 Buff Orpingtons) to make sure they had all returned to the run after free ranging in the snow.

One of my barred rocks looks bad. She is missing her tail feathers. I can't see skin but her long stand up feathers are just gone. On the back of her neck she has a number of broken feathers. Plus her usually bright red, full comb is dull pink and shrunken.

A couple weeks ago one of my BOs had broken feathers on the back of her neck so I was keeping an eye on things and didn't notice anything amiss until today.

Would a feather picker pull out another chicken's tail feathers? Could being feather picked cause her stress to the point where he comb looks dull and shrunken?

Can you post some photos?
Do you have a rooster?



I suppose feather picking could cause enough stress to have a reduction in comb size/color, but usually this combo is seen when molting.

If you can, observe them as much as you can to see if there is any feather picking going on. Check them over for signs of lice/mites.

Let us know how they are doing.

No rooster.

First picture shows the broken feathers on the back of her neck. Second shows her tail, sans her pretty black green stand up tail feathers and her comb.

Do you see any pin feather coming in on her tail?

The ones on the neck, it's hard to see, but it looks like she may have new feathers coming in.
