Thats not really what OP was asking about though.the best way to handle it is to always talk to local people about chickens and build your pool of options up of those that want chicks .. some people raise them for meat and will almost always take extras, and theres usually always somebody that wants 6 or so chicks to replenish .. so i keep the bator going pretty steady, 18 or so at a time to wind up with a dozen, and hand pick 3-4 occasionally to keep for my flock .. roosters i either give to those that raise for meat, or you cant be bashful about culling if called for .. when theyre first detected and small its pretty easy usually to let nature handle it for you and just turn them out, something will get them .. but sexing unless your running a business just isnt time or cost efficient .. running a modest size batch through the bator every couple of months will keep everything going ..
