2 year old BR hens, $8 each. I don't have any chickens yet and am looking for good layers. I don't know anything about the lifespan of chickens, how long they lay (assuming they're healthy and aren't coon food). Also, our coop/run is 4x8 and I'm not sure how many we can have in there. (pics on this thread: https://www.backyardchickens.com/forum/viewtopic.php?id=104157&p=1) They are selling 5 hens. Any help is appreciated!!!!
