Hi all, I know they are young but any idea what sex these babies are? I’m having a hard time determining whether boy/girl. They are 2 days old. Thank you!

I would recommend to post more pictures again at two weeks old but I think that you have two girls (1 & 3) with picture 2 a boy.

What you can try is to feel gently right above the genitalia for a piece of a basmati rice corn stuck right under the skin - the tiny penis shaft is quite distinctive to the feel while girls are soft and smooth in that area.

Thank you! We will try that!
 
When you post photos, we would recommend you use the forum software for uploading the photos, as the link to the photos showed a little more than we care to see on a pet forum! 😱 I've edited your original post accordingly. 👍
