Any breed of chicken should fine. I recommend getting female friends in a similar age range (5-8 weeks, give or take.)
You could even just get her ONE little pullet friend. Plenty of people raise just two little birds. Two makes a happy pair.
If you do get another little baby/babies any time soon, (which hopefully you do) make sure it is healthy before introducing them. Check all the orifices for any symptoms of illness, and under the feathers for mites.
Also, if you plan on keeping her until she’s an adult (or her whole life!

) she’s probably gonna want to live outside. A little coop might be a good idea sometime soon, because she’s now at the age where she can live outside and will want to.
My typical beliefs are that no functioning, healthy chicken should be kept inside and/ or alone. If you have an ill or recovering bird that can’t function outdoors, in a flock, then they are fine to live inside…but the thing a healthy chicken wants is to be rollin’ in the dirt with their besties.
So if you could maybe get her a friend, I think it would make her really happy.
No pressure. If it doesn’t make sense for you to take on another bird right now, she’s okay for a while. Just something to consider.
