Foal Halter should run automatically at 10 entries vs. 20. If shows have 4 entries, they will run at noon after 24 hours (just like regular halter with 7 entries). 

Why: It is nearly impossible to get 20 foals into a show, because the pool of available foals is constantly growing and shrinking. If you have a foal that is a 1*, 2*, or 5*, it is very likely that your foal's halter shows will never run, because the majority of babies born are 3* and 4* stars. This makes breeding the best possible quality actually a disadvantage. 3* and 4* will be ahead of 5* foals at age up because they were able to run their halter shows multiple times.
