Well I'm not completely sure, and I'm sure someone will come along and fix all the mistakes I make, which is fine. I'm just trying to get you by till some one who knows more can help out
I think they have something like 7-11 days to start out where they just bleed, but aren't quite ready to breed. then the next 3-7 days when they will breed. then an other week of a "post heat" sort of think. So I would guess that around 21 days of heat. I know I've read something about this on a website some where. If I wasn't so exhausted right now I'd do a google search for you
