So when it comes to culling I found Hyrim Canyon Stables website which for me was quite good! Now the thing is im not sure if the information in there regarding mare culling is outdated or if it still viable.

So, I wanted to ask some of you how do you cull mares?

This is the website page pertinent to culling https://hyrimcanyon.weebly.com/culling.html

thank you very much for any help!
