Rooster is injured by chicken

[New2Chickens2954]

A month ago- one of my chickens died and we had no idea why except that maybe she had been pecked by the other chickens. We waited til this week to add any new members to my flock just to make sure it wasn't illness.

I have a headstrong chicken. We are new to chicken ownership (5 months or so) so I am still learning. Two days ago my fiance got a rooster. My original chicken (very first one we got)- used to be the sweetest but is aggressive now that we've added new chickens and she's even pecked roosters before. This time- she full on attacked him. We checked the coop and she and another chicken had him pinned up against the corner of the coop- he was so still I thought she had killed him. My fiance went in to get his body- and he moved. He was bloody so my fiance pulled him out and she tried to attack my fiance! It was shocking because she's always very sweet and well mannered (for a chicken anyways ).

She used to be a free roam chicken and we are considering letting her roam again since she's become so aggressive. We removed the rooster and he's in his own area now until he heals and then I'm assuming its best to keep them seperated? If you have any advice I'd appreciate it.

How did you introduce the new rooster? Was it over time or did you just put him in the pen with the hens?

You are going to want to wash him and flush his wounds with betadine, chlorhexidine or saline then treat the wounds with Vetericyn or something similar. With that much damaged skin, I would avoid the products like bluekote. You can use hydrogen peroxide for the initial cleaning but don't use it after that as it damages new tissue.
He will need to be kept in a clean environment to heal. You can also apply a coat of pine tar to his wounds as that offers antiseptic and antibiotic properties as well as a nice barrier to flies and pecking.
How much space do you have in your run and coop?
How many feet of roosting space?
How many chickens do you have?
Do you have any objects to hide behind in the run?
Can you please post some pictures of your set up?
Many people are told it is fine to just put new birds in the flock at roost time. It is not. The new birds will be considered interlopers and will generally be driven off. If they can't get away, they will be attacked.
To successfully integrate new birds into your flock, it needs to be gradual and you need A LOT of space and things for the birds to hide behind to get out of sight of the higher ranking individuals.
Your boy can heal from these wounds with proper wound care.
You original girl is behaving rather normally for a chicken who's flock is being invaded by strangers.
