they will be fine boy, just don't expect too much, I bought 2 kits this time last year, and they were working by December, but as said I was resetting nets constantly, but by march they were working well, they seemed to have a look down the holes and then come back and then go back down and then the fun would start, and I did a bit last week for a farmer (I know out of season), and the went down no probs, but rats seemed to bolt out. With me mate, I dont ferret or shoot with anyone often, only if a few of us go on the odd day around new year or xmas so its just trial and error for me. Atb pal.
