Hens are fighting. Any help?

[PoppySeedy]

My hens have been squabbling for a little while now. My cuckoo maran pecks out feathers for fun (not in an aggressive way), my copper maran sometimes pecks at the cuckoo maran and recently my bluebell has gotten pretty agro with my copper maran.
Today I noticed my copper maran must've been pecked pretty hard by the bluebell and she got a bit bloody at the base of her tail, she's looking a bit scrappy at the moment (and I've got a saddle on her right now) but I'm thinking we might have to quarantine her until she grows her feathers back.
The only problem us when the other 2 hens are left with each other the cuckoo maran persistently pecks out the bluebells feathers.
I have 3 hens and a rooster as we only had space for 4 chicks, but I think one of the issues may be the lack of hens, meaning they all turn on each other? However I'm not too sure since I'm a first time chicken owner.
An idea im having right now to sort this issue is to separate the copper maran so she can heal, put chicken blinders on the cuckoo maran and hope that when I reintroduce the copper maran my bluebell won't pick on her anymore.
Is this a good plan?
I dont know if we can immediately just get more hens due to the lack of space and my parents unwillingness to help me create more space, but what are your opinions?

How big is your set up?

Separate the bully instead- that way, the BCM will have time to heal, and when the CM gets reintroduced, she'll get put in her place a bit by having to find her place in the pecking order all over.

How many birds do you have?
How big is your coop? Your run?
What do you feed them?

I agree. I'd separate the bully for a few days,, knock her alpha down a few pegs and asses my space and roosts. If I was limited on space I'd put in swings and hops, adding more room vertically and get-away spaces. I'd be sure to add snack bags for boredom. If I could I'd add another roost where the underhen can get away and get some sleep w/o a constant peck or being cornered.
Best of luck and keep us posted to what works for you so we can all continue to learn ♡

Never add more birds to solve a problem when the problem is "lack of space."

You did not include any photos of your set up nor detailed dimensions of coop and run. I have to assume they're too small and empty, if you feel they lack enough space, but we need to see what you're working with to give better advice.

Ditto Dat!

Here's another vote for photos and dimensions of the setup.

Also, if you only have 3 girls and a male you are likely to have overmating issues -- especially if said male is a young cockerel with poor technique.
