I have 4 polish, can you post a picture? I can probably tell if it is a roo with some certainty at that age.
Good luck with your bird yawningreyhound. Sorry, no experience with that vet.
edited to add....you know how polish aren't supposed to be broody? they are my MOST broody birds, maybe even more broody than my bantams!
Thanks for the feedback, I'll post photos this evening, but after this morning's sun salutations there is very little doubt that I do indeed have at least one cockerel in the bunch. I shouldn't have gotten attached to the little guy and his punk rock hair...Mine are very chatty, but it's a wicked witch like cackling or a purring noise when they're getting ready to lay eggs.
