Raspberries, at least the usual kind of summer raspberries, should be pruned immediately after fruiting has finished in mid-summer.
If they are growing well and flowering, they should also carry fruit. It may be that birds are getting the fruit. If flowers from but no fruit, the plants may have virus disease, although this usually affects vigour and the plants are usually ten or more year old.
