I had to double check, bc the conversation is so familiar that I thought
@R2elk was punking me with one of our old ones.

Yes, I have a reputation for "tame guineas". I don't particularly see them that way- but I don't have chickens to know the difference.
I've had 2 hens hatch, and I let the hen raise them until I sell them. But If I buy them, then I raise them, bc they're mine.
They're raised amongst the household and everything in it, us, the dogs, the tv, the noises. They're used to being handled,having their feet washed, nails trimmed and hand feeding. They grow up having snuggle time with the dogs and me on the sofa.
Numi loves her showers, as does Willow. Those two, as adults, I still bring inside once in awhile, whether for their benefit or mine. We still congregate on the sofa.
There are 2 remaining male jumbos- one I hatched and raised, the other was Mama's, and refused to be sold. Eventually, even that one got used to being handled and having his nails done, but he is still quite wild and spends some nights up in a tree during freezing temps. Not often, but sometimes he gets an urge. No one else has a desire to be outside at sunset. Both of the jumbos love babies, whoever they belong to.
I remember being warned about imprinting. I've not seen that to be a problem. Everyone moves into the coop and becomes flock members. Numi lived inside for several months, moved into the coop, mated and raised her 1st hatch last year.
I had a jumbo male who didn't trouble himself with fighting the other males, he didn't see them as competition. He startled me one day his 1st season by sneaking up behind me to bite my leg. It didn't hurt,didn't break the skin, and he never did it again.
I'm not sure what the OPs goal is, since I know squat abt chickens. There are several who have a house guinea. One walks hers on a leash and takes him to school for visits, in a diaper. I guess some show them. Numi was appalled by the idea of a diaper-and never had any accidents. Willow isn't quite that advanced. They have their own blanket to lay on when they come in,just incase.
We got ours to work for us for tick control. We spoil them rotten, they have the fort knox of set ups, and we're crushed when we lose them.
Tricks? Mama taught them this - she did love her celery -
But - I spend A LOT if time with them. I'm a grandma that babysits and my daughter is a teacher. So when keets come along in the summer, I have that time to spend. The rest of the year, the one thing I insist on is my free time. Some women shop, I hang out with the animals.
