The lowest pullet in the pecking order who was chased and pecked by the others was the first to start laying and now seems to be at the top of the pecking order...is this possible? She is a Red Star, she's my friendliest and her demeanor has changed now after laying a couple eggs the past two days. My biggest pullet (a Buff Orpington) was by far the most dominant and has been following the Red Star around but defers to her now. And now the BO is fighting with the others. Can pecking order change as the girls start laying?
