When is the last day of breeding for a mare?

Hi all, 

Just a quick question as I cannot seem to find of anything has changed the past few years over the breeding or mares. When is the last possibility to breed your mare nowadays? 

After a few years I have returned (found my old foundation stock of Shetland ponies ♥) and try to see if I can keep up with all changes of the game. I think I understand NSS now, not still not too sure about breeding for conformation though. We will get there.

I am also trying to re-evaluate my pairs of Shetland ponies for breedings, and try to choose if I want 1 or 2 foals from my mares (and to keep the same pairs or change those up as well?). 

Any input would be greatly appriciated.

Thank you all! :)

hello, the last day of breeding should be when the age shows up as 20 years (ages tomorrow) and the mare is off cooldown as well.
as for foals, it depends on what you want. since breeding now can randomly lower NSS, it's more desirable to have multiple foals from the same pair and pick the one with the lowest NSS to keep for yourself. but it's also fine to just have one foal per pair if you want.
good luck with your Shetlands! ♥

Thank you for your answer Forgotten Land!
I am thinking about 2 foals per pair in this moment.
Still debating if I should keep the same pair for both foals or not.. First intention was to keep them paired (and not mix the pairs), but as there are so many possibilities I need to gather more infomation first. 

Thanks ♥
