Older hens killed pullets

[Chikkenmamma]

we had 4 pullets about 8 weeks. They’ve all been integrated for a few weeks. Things were going well. Not much bullying just the odd peck here or there. Yesterday we found two pullets scalped. One dead and one almost dead. I can’t say it was 100% the older hens but that’s what I’m guessing. When I checked this morning she was gone they were the sweetest chicks! I’m not sure what to do with two other pullets. I pulled them for the night in fear of them getting attacked. Do I get more chicks to make a larger second flock? I thought two wasn’t enough. How long to keep them separated?

What is your run set up like? Do they have enough room / clutter for hiding and creating “separation” / multiple feeding and watering stations?

We have four pvc pipes for eating inside the coop. And one hanging 5 gallon water with four drinking cups. Large attached run

How large is “large” in feet by feet? @aart has good information on integrating younger birds in with older ones.

And they free range wetlands almost every day.

How old are these chicks?
How did you add them?

Dimensions and pics of coop and run would be very helpful here.

Photos of the set up overall would help. Even after integration you still need clutter as well as feeders spaced apart to prevent fighting over resources.

Personally I would assume predators or accident were the cause of the original injuries, unless you actually see the hens initiating the attack. It's normal if the hens start pecking at injuries after they happen, but does not mean they were the initial cause.

I agree that if you're using the word scalped it sounds more like a weasel or some other predator found a way to reach in without actually being able to get in. Or possibly the pullets stuck there heads out a hole that's too small for the hens and a raccoon attacked them.
