Congratulations on your polish babies..
I have a 1 1/2 yr old white crested black polish roo who is the most stressed out poor bird I have ever seen.
He has 3 hens and he attacks me unless I carry a green towel with me into the pen..Poor guy just will not relax and just be a chicken without running around crowing every 2 or 3 mins for most of the day ,until they go to bed..
When I look back at it, before we knew if he was a roo or hen, he was a little aggressive for a little chick.
I love him unconditionally. He is such a good boy for his girls which is more important than whether or not he is one of my fans..lol
Enjoy those babies...
