That actually makes a lot of sense! And you know, it's actually sort of funny because I'm really into dogs and dog training and stuff too, at least with my own, (haven't done it in a while though, gotta start again), especially the positive and behavior science bits and stuff, and I sort of knew that for dogs, like for example how if they juml and you yell at them, that is still attention that they want and will do it more so to ignore them totally, etc. Yet I never thought of applying that to chickens xD I'm going to try that! Extermination, from what I've read, can be really powerful! Really hard because if you do it even once every 100 times it still gets reinforced and they keep trying, but powerful if you can actually manage to 110% stop reinforcing it, so I think I will try that! And try to pick up training the dog again! Harder with him though causw my dad thinks practically every rule is mean and lets hkm get away with nearly everything!!!! Or enforces it once, gets mad another time! Like play biting or jumping up, paws on shoulder, and kissing him. One second or day it is cute and funny and next time he wonders why he keeps doing it!!!!! Anyhow, sorry to ramble, but yes, definitely harder to unlearn behaviors than to do it right from the beginning! Especially because at least with my dog, he will test you to see if you mean it. Even if he knows it. For example, a long time ago I taught him to stay out of the kitchen when we eat and he gets something at the end. I stopped enforcing it all year and inconsistently enforce it now. He gets up and comes in numerous times before settling. He's better now and if I tell him down he will stay. Unless something more interesting happens. But if I just tell him out and not to lie down he will come in. But the first few times I started reinforcing it, he would get up and come in soooo many times until finally he realized I meant what I said and now he will stay. Again, we still have issues with staying when more interesting things come up but we always have. And the interesting thing too is he will run straight to my dad or brother who never did it (and brother has different ideas for when and how long it should be, unfair even) so when they enforced it he took it way more seriously. But now that brother is back at school so when I try to get the dog back put, he does laps around the kitchen and runs straight to my dad WHO THEN PETS HIM.
