I'm so glad to hear Rocky came through everything great!
. But I too believe that Rocky is a fella, a very pretty one but a boy all the same.
I know that aligators and the like have claocas (sp) but inside they do have real boy parts , that chickens just don't have! LOL So not sure how she checked the sex that way? Anyway I'm so glad that he came through everything like he did, and that he had you there for him.
