I didn't know you could train a chicken not to poop on the bed LOL.
I second that the chicken should see you first when they hatch so you get imprinted as their mama. We had the 2 roosters that hatched the second try in the kitchen. They were used to the lights and noises, when they could fly out of the box we let them walk around in the kitchen. We handled them a lot, fed them by hand but never restricted them when they didn't want to be held, just gently encouraged them to stay where they were and we talked to them a lot. I peeped in a high pitched voice like they did and called them the same names every time I talked to them. One of them were handled roughly at day one when I thought something was stuck at the bum, it was the umbilicus (I know that was idiotic, we didn't know what we were doing), and on the next day when we tried to check the sex from the wings we must have pulled the feathers because he ended up with a crocked wing, he does not like to be handled at all, but he follows because the other one is his brother. The one that didn't get hurt at birth is tame as can be, he follows me everywhere, he hides behind me when the hens are chasing him, he eats out of my hand and sits on my lap, he puts his head down and sometimes falls asleep. By the way he is on my picture and his name is Peck. I noticed that hens peck him more when I am more attentive to him and I let him eat out of my cup, or I protect him more than the others. The hens pick up on this and they don't like it. He is 4 months now. I think they need a lot of attention like any other animal, and maybe more because they have tiny brains and they forget or instinct kicks in and they can become skittish and run with the hens. It is true they all have their personalities. I have a hen that I got at an auction and she discovered elite treatment when she is near the 2 rooster kids so she is always under my feet to get best seat, she is Dusty. Another hen from the auction is always by the door, curious to see what we are doing and she is literally looking in the glass of the door, my sons call her Explorer 2.0 and she is friendly too. The rest of the hens and roosters must have been treated badly or not handled at all because they are frightful and some are outright mean, but they are better now since I spend so much time in their yard talking to them or just sitting and watching them. I stroke their backs when they go to sleep and I talk to them so they know who is touching them and they are getting used to it. They are fleeing less and less, but if another chicken is startled and runs, they all run. Like I said they have little dumb brains and run like crazy.
I can't find the picture where he actually closed his eyes and fell asleep but it was at the same time I took this picture:
