Currently I have 9 hens, 4 chicks, and some temporary meaties. I have the opportunity to take on as many as 12 other 1 year old hens. My coop is 12x18 and I have an attached run that they don't use-they prefer to free range in our yard, fields, and woods. I know you should quarantine the birds first for about a month, is there anything else I need to know? Will they try to "run away" or will they know to stick around a strange invironment. Will they just start using the nesting boxes? Anything I should watch out for? Thanks for your help!
