I've been teaching mel's chicks not to cross the raised black line I have on the floor between my bedroom and the rest of the house.
I used to have a small amperage electric current running through a wire under the tape; not enough to shock, but enough to detect.
None of the adults cross this line (well very very rarely) and the chicks naturally watch were the adults go.
O must admit, I feel a bit of a fool pointing to the line and telling the chicks they are not allowed to cross it, explaining that that is my perch space having steered them to the permitted side.
The strangest thing is it seems to be working.
