BCM chicks around here go for 8 to 10 each. Started pullets go for around 25.00 unless they are hatchery birds. Hatchery BCM go for much less.
BCM seem to average about $10 a chick for day olds. I have seen pullets & hens go for about $30-$50 depending on age and quality. Usually older birds being sold off are culls and have some issues that you wouldn't want to breed but would be alright for layers.
