Hi there, In a few weeks, I'll be buying chicks at our local feed store for a very small backyard flock of three hens. The store ordered sexed chicksten each of barred rock, BO, and Ameraucanaand I will be able to pick out the ones I want. I only have space for three chickensmaybe four, though I think it's a stretchin the coop I am building so I really can't give in to Chicken Fever. With that in mind, how many chicks should I buy? I'd like to avoid having a bunch that I need to re-home later, but also don't want to end up with two hens.
