GWs stoick and intentional
B&Gs comedic and candid/ in the moment
Scarlets mercurial and aroused
The intentional, candid/in the moment, and aroused behaviors may be what you or others may personally deem nice/ gentle/ fun/ overall positive or they can absolutely be what you or others would deem unbecoming behaviors.
Which is more prevalent is contingent on each individual bird and then it becomes situational from there (health, diet, sleep, overall husbandry, and training taken into consideration)
I'm pretty much team GW but own and enjoy my B&G and very high scarlet content hybrids (HCC and Capri) in the family/flock as well.
