Why is she being this way

[Cwashelesky]

I have a white rock hen an she was scaredy cat but fine until my other hen had chics an i also bought some chics now she is very aggressive an she has injured 2 chics very bad. Why is she being this way? Shes a decent egg layer an I'm afraid I will have to get rid of her.

Adding to the flock can cause chaos....especially in a smaller flock
She's defending her territory.

These tips might help you find a solution.
Integration Basics:
It's all about territory and resources(space/food/water).
Existing birds will almost always attack new ones to defend their resources.
Understanding chicken behaviors is essential to integrating new birds into your flock.

Confine new birds within sight but physically segregated from older/existing birds for several weeks, so they can see and get used to each other but not physically interact.

In adjacent runs, spread scratch grains along the dividing mesh, best if mesh is just big enough for birds to stick their head thru, so they get used to eating together.

The more space, the better. Birds will peck to establish dominance, the pecked bird needs space to get away. As long as there's no copious blood drawn and/or new bird is not trapped/pinned down and beaten unmercilessly, let them work it out. Every time you interfere or remove new birds, they'll have to start the pecking order thing all over again.

Multiple feed/water stations. Dominance issues are most often carried out over sustenance, more stations lessens the frequency of that issue.

Places for the new birds to hide 'out of line of sight'(but not a dead end trap) and/or up and away from any bully birds. Roosts, pallets or boards leaned up against walls or up on concrete blocks, old chairs tables, branches, logs, stumps out in the run can really help. Lots of diversion and places to 'hide' instead of bare wide open run.

Please post pics of your setup maybe we can make some suggestions.
Also...how many birds total at what ages, please.

This age difference requires two separate areas until the chicks are at least 3-4 month old.

Of all the hens I've had, there was just one that would NOT leave a broody and her babies alone. She's the only one I ever had to rehome (I don't sell my pullets- except this one) - she wound up in the city where people are limited to three birds and did fine with her new companions and no chicks to torment.
