In my flock (16 hens, 1 roo) there are 5 old hens (4,2,1 year old) with their pecking order very well established. They are dominants to all the rest of the pullets. In this pecking order (6 Isa B. Reds and buffs, and 5 mutts all starting to lay) the things are more confused. There is not one pullet who is in the bottom. There are 3 or 4 who are there ,but they all interchange dominancy. For instance A peck B,and , D, but C can peck A, and so on.....I have always notice this, in flocks with numerous birds. What is your experience?
