Thought I'd post an update.
I'm certain now that I have a boy named Sue.
The search is on now to find him a new good home. Where I live I can have roosters, so I have time - don't have to freak out about violating codes. I'm off today to put up a flyer at the feed store.
Wish I could keep him, looks like this is going to be a gorgeous bird.
Irene is looking more and more like a hen every day so good news there.
I purchased 6 eggs in July, five of them hatched. I have these two Ameraucanas and 3 Mille Fleur Leghorns. Seems I have been extraordinarily lucky (from reading forums here) we only have one rooster out of the 5 chicks.
