Thx, i'll try to offer earthworms again. Like i said , he was very interested in the worm but he dont touch it. I will try to vary its food this summer, all fresh :) Then if in the next winter, fresh food is less available, i will return to trout strips ;) I often found slug in my garden, can i offer those too ? Dont worry, no pesticide or anything (kind of wild garden :) ) Aint the slug a bit gooey ? or sticky ?
