RE: dusting areas
Turkeys dust to remove parasites, feather mites, losue, ticks, other insect critters. It is the way they take a bath and I have seen them dust in all three seasons except Winter.
Dust bowls are a very good indication of turkey sign. I purposely look for areas tht they use. Ocassionally you will find a dust bowl that was made by a single hen. What you need to find are multiple dust bowls or major dusting areas and use only them.
We have found one area that just immense dusting area. Looks like they had a communal bath and is used by multiple birds.....each year they return to this area and is a good area to sit and wait.
