Small goats, any chance they will catch up in growth?

Really need to know the breed here, if they have Pygmy or Nigerian dwarf in their line you aren't doing so bad. Sometimes the other breeds get in the mix back there a ways.
Depends on how much weight you want to put in their packs as well, the smaller guys could probably handle some of the bulkier light equipment.
Like sanhester said, heart is more important in the end.
