Black Australorp hen is crowing? Hen or late bloomer?

And even with 1 roo to cover 24 hens, his favorite gals will be feather worn. At least that has been my experience.

Regarding your leghorn, I added some of these to my flock this year too. Just so I can get white eggs.. Side note is I read repeatedly they are a skiddish, flighty breed. And in my experience, they are.

They certainly are!! Sunshine (the one in the pic) will come to you, but the second you move she's off. They are such beautiful birds though!
