I don't think I said they were equivalent. If I did, that was a typo. What I meant is I view the level of challenge in this order (near the end of the season too):To say that an unpressured private bird is equivalent to a pen raised bird is not even close.
Public land birds > private land birds > Pen raised birds
How much each is greater than the next lowest type of bird is subjective and has a lot of variables at play. And not every bird in each bucket is going to behave the same as every other bird in that bucket. Could even be some overlap with a small percentage of birds between one bucket and the next, I suppose.
