Send a message to all your liveries offering them the best rates and able to work where there horse is stabled, some people forget it is only pretend and jump at the chance! You can hire temporary staff but more costly in the long run!
I have a few and several two star mares but I am working hard with the Connemara ponies now as well so not as much time to breed Arabs!!
I still have around 75 horses (all arabs except the old horses I buy to earn passes), and my EC has just topped one million E's!! I am also having trouble finding riding instructors and vets. I only board my own horses there, so not too bothered getting a vet - just move pregnant mares to another EC until foaled then fetch them back.
