Have a technical question you can't find the answer to in FAQ's? Ask it here. Game problem questions that do NOT pertain to things like training advice, what would my horse do well in, how much is it worth.
Is it really bad to inbreed a horse? Like will the foals be ruined? I have a Foundy pair and I am soon going to have 2nd gens but I don't know if I should wait until I get another foundy pair?
There are absolutely zero downsides except for aesthetics. Some people freak out when they see horses bred together are closely related, but it won't do anything negative to the foal.
