Smaritza,
If the Hardy chicago was purchased, and not repotted, it may be root bound. The other plant may just need more water.
I always politely introduce myself to the owners. They have all been friendly, If not a little wary of me asking about their fig trees : ) But after polite conversation I'm usually invited back for figs and cuttings or even rooted suckers. One of the important questions other than the fig name and place of origin is the time that the figs start to ripen (so you can come back for that taste). Good Luck.
