I've got a problem. We have had a recent outbreak of egg eating. I love my girls, and I don't want them to end up in the stew pot. So, having a Ph.D. in Education with a solid background in psychology, I want to approach this scientifically. So when you're trying to shape behavior, there are four ways to do it: positive and negative reinforcement (add or subtract something to *increase* a behavior) and positive and negative punishment (add or subtract something to *decrease* a behavior). Neither positive nor negative reinforcement will do the job, because those would be for increasing the girls' behaviors, and we want to decrease (to extinction) the behavior of pecking on eggs. So we're down to positive and negative punishment. I either add a negative experience when they peck the eggs or take away a positive thing when they peck the egg. I can't be there to take something away. BUT... I got some nice wooden eggs in the mail today. I'm thinking that if I could just coat them with something like what you'd find inside a blasting cap, or bang snaps or throw bangers--those things kids throw on the ground and the explode. Just a little explosion. Enough to make you back up a step or two, right? Anybody else see this with me? Or am I just an evil chicken mommy? PS: It's really hard to get a chicken wearing a sign to STAND STILL.
