I only had two sisters, they'd spent their whole lives together. They were around 3.5 years old and last night I lost one to a dog attack. I am devastated. But I am adamant that I need to provide my remaining hen with companionship ASAP as I do not want her to be lonely and become increasingly depressed. My question is should I add another adult or a young chicken. Should I add one or two or three. I certainly have the coop and yard space on the property so that is not an issue. I am looking for the easiest transition for adding them. I'm wondering what would be best, age wise and how many. I dont mind adding just 1 or several. To add: I've done my research about quarantines/introduction strategy, so my main question is what would be the ideal age of new flockmates to add, and how many to add. If this is a good opportunity to add more than one new one, I would like to. But I dont want to do it if it will increase anxiety for my single remaining hen, who has been only living with one flockmate for the last year.
