Yes! I have definitely noticed this since my flock came down to being only 3. It is now all much more complicated with more shifting of positions. It all seemed very set and calm when there were four.
I will want to get back to 4. The flock was more balanced. I had 3 for years and it just seems to work better with four. No one is ever out there on their own and the pecking order enforcement was much lower. The whole flock was calmer.
It's a shame really because the pairings had just started to switch up from time to time as well. I was seeing a lot more of Hattie paired with Aurora and Mal paired with Lilly.
