Telling someone they have a rooster...

[Iluveggers]

A picture would be easier. What colour were the legs?? I know you can get cuckoo leghorns so that could explain the early developing of the wattles and comb

I don’t remember the leg color. Maybe I’ll ask to get a picture of her run or something next time & sneak one of him/her.

That would be a good idea

Well, if there is an opportunity in conversation where you feel comfortable telling her you think it might be a boy, then do it. Don't just say outright that it is a cockerel, because then it becomes a challenge, and she may give you a bad reaction. Just suggest it. And if she insists it is a female, then drop it.

Often people need to figure these things out for themselves. She's gonna know in a few weeks when it crows, anyway, so you're not doing any harm by keeping what you know to yourself. I guess I'm saying that you should follow your intuition based on what you know of your friend's personality and her past behavior.

If you do not feel comfortable telling her, you can just not say anything. She will find out soon enough.

This.

If she didn't ask for your opinion it's probably better to not offer it.
