Hello,
Breeding is a "harvest" task (like prospection), not a craft one (like forging).
You need a pen (see Landscaping :
http://www.theriansaga.com/guide/skills ... 2bcb902040) or a barn (see Construction, same page)
With a barn, you will be able to transform harvest products (see Breeding :
http://www.theriansaga.com/guide/skills ... 2bcb902040) using the "production" tab (see Production, same page).
