I've been cruisin a couple of hatchery website and noticed that the price for cockerels is about half or more the price of pullets or straight run. I normally get White Mountains or Vantex for my meat birds, but some of the multi purpose birds would probably be fine (at half the price) as long as the cockerel would be of comparable size. For example, my Isa Browm girls are huge. Will the cockerels get as equally large, in the same comparable timeframe? Looking for suggestions. thanks
