I am so sorry to read of your loss
I used to have 2 chickens but now I have 5; one of the reasons is because, having lost some in the past, I do not want to go through what you are now with a lonely chicken.
Cilla, my matriarch, is the remaining gal from my original two. We lost her friend Ash and she was distraught by herself so I had to rush out and buy her a friend. I
do not recommend waving quarantine but because of the circumstances, I did on that occasion and introduced her and the single girl immediately. Because they were both alone and in need of company, there was very little pecking etc and that night, they roosted together.
Unfortunately, only months later, Cilla lost that friend also and was back to being alone .. another mercy dash and Brittney was welcomed and immediately introduced .. again, no real problem and they were best buds pretty quickly.
So that neither the chickens or I had to go through that again, a couple of weeks later, after quarantine this time, I introduced Dusty.
So, in my experience, if you have a lone chicken and introduce a lone chicken, the chances are that their need for company will outweigh the need to
pick on each other too much.
Then, when ready, you can introduce a few more, after quarantine.
Again, I am definitely not saying that waving quarantine is a good practice and certainly would not do it now with the 5 girls I have but, at the time, it was a risk I was prepared to take.
