I would have guessed that they didn't foam. I dont vent sex so I dont know to much about it.
Well I suppose the only way to know for sure is in 14 days from now ,when the eggs in the 'bator I got from this pair are supposed to hatch
No red coloring around the vent ,however "he" is smaller then my other hens and does have a very strong crow/contact call ,compaired to the hens.
He's a blue face ,so he shouldnt have a red vent ,right ??
