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

[Kelpy]

So I got 6 goats about a month ago. They are all at 1 year old and they weigh 95, 87, 83, 77, 73, 68lbs. I didn't really think about it at the time but after a little research it would seem that they are way behind in what most packers target for a finished weight. Will they catch up or should I be looking for some replacements? They were castrated at 4 weeks I believe, will this affect the growth rate?

Lots to learn and I may have taken the plunge before I knew what to look for. .. thanks
