You can have as many stallions as you want in your stable. That being said, if you already have an stallion (Winter, White, Black &/or Black mini) and you attempt to shelter a Wandering Stallion, THEN you will get an response that you are already have a stallion in your stable.

Increasing Your Odds of a Foal I have noticed, the only thing that increases your chance of getting foals is the greater the percentage full. (i.e., stable capacity) If you stable capacity is 20 & you have at least one stallion & 19 mares, your odds of getting a foal are very good. Better at higher capacity (i.e. 40 capacity with at least 1 stallion & 39 mares)
