If you drop your upgrade, your primary barn size will go back to whatever level you are dropping down to, plus any bonus stalls you have earned based on your member grade.

The features of the Advanced Breeding Lab all cost a set amount of hbs and Performance Testing and Papering all cost hbs too.

It costs 500 hbs to collect each straw.
There is a 3000 hb vet fee to use a straw on a mare.
If you have a basic upgrade and can use a straw to create an embryo from one of your mares directly, in which case the embryo is removed from the mare and frozen for implanting later in a surrogate mare, the cost is 8000 hbs.
It costs 4000 hbs to implant the embryo in the surrogate mare.

If you have a premium upgrade you can collect eggs from your mares to use creating embryos.
The fee for each egg you collect is 3000 hbs. Also, if you wish you can flush your mare of all available eggs. This costs 125,000 hbs and results in 8 to 14 eggs.
It costs 2000 hbs to create an embryo using an egg and a straw. The implantation fee is the same as above.

Performance Testing costs 500 hbs.
Mare Papering costs 2500 hbs.
Stallion Papering costs 1500 hbs.
If you have a premium upgrade you have access to Strict Mare Advice, which is free and as strict in its parameters as Gelding advice, and the cost of comparison testing your stallions drops to 4000 hbs from 8000.
