Hi welcome. We started of with five hybrids in a run in the garden, I now have about 35 (at the latest count). We now have an incubtaor and (cross)breed or own birds (eat the males), but I would recommend to start with birds at point of lay (POL's). That way you can learn all about them from an age where they are much more robust, start to lay eggs for you soon. When you hatch out with at least 50% males usually immediately you have to make decisions about them etc etc.
We also rear meatbirds, that we buy in as day-olds, and we have had good success with them.
