Ok, so the first 4 I’m afraid may all be cockerels, or maybe 3 out of 4. The 2 barred rocks were supposed to have been sexed-pulleys, but I think Bertie is a Bert. Myrtle looks ok. Tweetie and Poussey may be Roos also, what do you all think? Tweety and Poussey were “chest bumping” and flapping their wings at each other. (Btw, my grandkids named them).
