Why cant you get a chick right now?
the time alone will still make your chicken lonely, depressed, and stressed. Its best to get another chick right now.
Buying another chicken later is better than raising it alone, but they will probably fight and will never be as bonded as two chicks raised together
They won’t fight, for years I have bought older hens and NEVER once has there been fights....pecking order gets established, but that is not a fight, cock fighting is a fight....
In a perfect world yes have more then one, but these are fowl...like having a single love bird as a pet, they bond strongly if in pairs but are perfectly fine and will bond with their human if single bird.
