New Sow Dominant?

[BambiPaws]

I have 4 sows.
Squeak is 4, Bambi and paws are around 7-8 weeks and Cocoa (new sow) is about 5 weeks old I'm guessing.

I introduced them today and it seems Cocoa is the dominant sow.
She's tiny compared to the others but all of them have submitted to her.

Is this normal
I thought it'd be completely the other way around.

Size has no bearing to hierarchy order among piggies

Hope they are all settled with each other

It can happen (we had baby Hadley be dominant over giant 4-year-old Sundae, even though she was less than half Sundae's size and weight at the time.) Dominance has far more to do with personality than size, and sometimes more to do with personality than age. Some pigs are driven to be the boss, others don't want the role at all.
