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

[Nanno]

Depending on their breeding, if you can make sure they're worm-free and if you can get them some good grub, fresh air, sunlight, and plenty of room to play then I see no reason why they won't catch up. I bought a 9-month-old Alpine/Nubian buck last year who couldn't have weight more than 70 lbs. when I bought him. My 6-month old does were half again as big as he was! I was sure he would be stunted for life, but within a few months he had passed up the girls and is now on track for being as big or bigger than Cuzco! I also bought some 2 1/2-year-old Alpine does last year who were terribly under grown, and I was sure they were too old to get much bigger. But they've actually grown quite a bit (they'll always be a bit stunted), but I've been amazed how well an undersized goat can grow if given the opportunity to do so. Their bodies want to live up to their genetic potential.
