I have eaten small and large boars up to 300+ pounds, sometimes the small ones are too strong to eat, I feel it has more to do with whether or not they are breeding sows. You will be able to tell whether they will be too strong to eat by the time you get w/i 10 or 15 feet of them!!! It helps to leave them in the ice chest for 3 to 4 days, just keep draining the water off and adding more ice. Hogs will breed at any time, but it will normally be focused around 2 different times of the year with the majority being born in late winter and early spring, with this said, most hogs in our area are breeding in late summer and early winter. Regardless of how strong they smell, I have yet to waste one, someone will always take them. I just do not believe in shooting something and letting it lay.
