I would like to place some input here. I trained my imprinted shikra like a passage bird. The way I do is to use forceps to hold tid bit so hopefully the bird will show aggressive toward the forceps not my finger. If I put the reward on glove then it has to be very small that my shikra can eat in one go to prevent mantling on my fist. I also do not reduce weight more than 5 gram a day. After recalling distant is around 30 m. I then introduce the lure. Usually the whole process of recalling is less than 2 weeks. Many will take less than a week to free fly. However, entering is more difficult for shikra and frozen baggy of the bird you hope to hunt is very helpful. I hope this help.
