red currants

I had a large handful of red currants with my breakfast ceareal this morning.

I have 2 red currant bushes in my garden, both in their second year. Although only feet away from each other, alongside the western fence, there has been very different results.  One has had its leaves badly eaten and has had no fruit.  The other leaves are fine, and I got the large handful of currants - disappointing though that that's the entire crop!
