Yes, your Polish is a cockerel...
Boy, this is interesting. Not sure if it is relevant or not. It almost looks like down collecting on the eggs from the first chick.Just thought I'd share a pic of this cutie! Isn't he doing well? Just wish he had some friends to join him!
The other eggs have all developed this funny speckled pattern which has me doubting they're any good but planning to candle later on when it's a bit darker
You may want to consider checking around locally and seeing if you are able to find atleast one day old chick somewhere for company. Chicks who are alone can develop a pretty sever depression.
@Kiki may know more about the condition of the eggs.
