I have 2 green cheeks and a recently adopted Sennie.
Ernie is a definite sweetheart, but his beak is something to watch out for! He does give more of a gentle warning nip than the cheekies. We are still learning his mannerisms and moods. He will go to just about anyone, but preferences are flopping back and forth between Hubs and myself. He loved Hubs last week, this week I am the Chosen One. He pierced Hubs ear the other day in a temper tantrum over going back to his cage.
Hormones have hit and he has had a big temper. We are curbing that with an early bedtime, no nesting spots or huts, changing up his foraging items, and changing the cage around to keep him on his alert little toes. Nothing major, just moving his toys around, or adding something new to it. That area is much different from conures.
Rhoma and Rhema are more independent, but they are both "rescues", adopted from homes with very little interaction at all. Rhoma likes to play games and get head scritches, Rhema is more content to fly around and left to explore as long as someone is in the same room with her.
When Rho and Rheems bite, there is a more firm warning and the bites are not as hard, but blood will be shed if you do not heed the first warning. Hormone seasons have been pretty easy on attitudes as long as men do not attempt to touch them or their "things". No nesting spots allowed and if there are toys they regurge for, it is removed for the season.
I will probably never let the Sennie out with the conures for safety reasons., but I will eventually be putting all cages in the same room.
All birds are different. I would say let the bird choose you.
