Very informative thanks. My polish chicks are 4 weeks, one has struted around from the start and fusses whenever we hold any other chick so we will be surprised if it turns out to be a hen! Got lovely pompom heads already, have black and silver white crested and a all creamy/white one we thought was a frizzle but not so sure at this stage! Will try to put up some pictures but they don't stay still long enough and have tried several times lol!
