A couple of possible niche's to consider --- started chicks and/or POL pullets. For these to work you would have to have the ability (and costs) to feed and house the birds to certain benchmarks of age that make them desirable to folks looking for birds. Started chicks are those that have been raised beyond the point of needing the brooder and are ready to go outside - some folks like to skip the brooder stage. POL (Point of Lay) pullets are females that have been brought to around 16+ weeks of age and are near the point where production would begin. These birds are attractive purchases because a) they are beyond the point of "maybe cockerels" for most breeds and b) the new owner is just a few weeks away from getting eggs vs. being a few months away. Each of these types of birds command a higher sales price than the day-old chicks available from feed stores and/or hatcheries (note some hatcheries do offer started and POL birds) - but it will be a matter of sitting down to figure your costs and see if the resulting price point is one that could reasonably be expected to be gotten from the birds at the point of sale or not.
