1: The studs/mares can be a lot of factors to be honest and cannot be pinpointed to anyone factor as to why. For me, I mostly have my own bloodstock, stocked up and I rarely look to outside, unless I'm looking for something very specific that I don't have or want a better version of. Someone else could possibly expand upon this over me.

2: Are you breeding horses, all willynilly? Most people prefer to have foals with a training boost of 10, meaning the stud/mare have to be a minimum of 50, or some other variation, as long as when you take the two numbers, say 50 + 50 = 100, then divide that by 10, will give the training boost the foal will have, in the very end, once foal training is complete. Some people are even picky about genes too and looking for specific colors to add to their stock. Some folks, don't like graded horses, as it takes longer to show in Disciplines over Halters, as Halters give you more exp, depending on their ranking in Disciplines, as some folks, switch to Disciplines around Tier 2, Regional(?) I think it is. Random crossbreeds, thrown together, without any crossbreed campaign behind it, can also make some people not interested, for the above reasoning, harder to gain levels etc.

3: Clubs can be hit or misses, because outside of crossbreed campaigns? Clubs really don't have much of a purpose, truth be told. Some have tried to use clubs to help others or just do fun events, but they have, sometimes, faded away.

Sorry to hear that you are struggling! Here is some of my advice…

First and foremost, the best way to make money in this game is to show/work your horses everyday. So either entering halter shows, competitions, etc. I have found that it is the best way to generate revenue! 

As for breeding goes, it just depends on what people are looking for. Most people tend to look for higher level horses to have a higher training boost foal while others are looking for unique genes/patterns. I find that plain, lower level horses, don't always drive in requests/buyouts. Plain horses, overall, struggle to get bred. Some people are also looking for specific breeds, and some are more popular than others, I find pretty good success with my Irish cobs and mustangs because they are pretty popular, whereas my other misc breeds will go days or weeks without a buyout. 

As far as selling goes, again I find it hit or miss. Sometimes it takes a couple days (or weeks) before someone comes along. You could also try lowering the prices or running auctions. If I have trouble selling a specific horse, I will sometimes auction it off. Horse sales also depend on the breed, again the more popular it is, the better it sells. I had a nightmare trying to sell my Welsh Cobs D, so I shelved that project temporarily. I also find that purebred horses sell better than crossbreeds! I could never get any of my crossbreed horses to sell!

As far as clubs go, I don't have much advice because I have very little club experience. It seems like the best course of action is to find a club that has a lot of members/active members. As both a mustang and Irish cob breeder, I see a lot of folks breeding Cobblestans from my stock, so I assume it is pretty popular! But again, take my club advice with a “grain of salt” I am no expert.

Thank you both for your suggestions 🙂 

As far as breeding goes I do breed sometimes just to breed but sometimes I breed to sell and if I see that I have any older horses that I am going to retire as in if they are up in age as in nearing in their 20's and see they have good pedigrees then I will breed them one last time and I will seek out upper level horses to breed to in order to try to improve whatever foals I have from those crosses.

 With training I train every day or try to when I care for horses and even have some as model horses to earn a little bit of money
