Total newb here with 4 day old silkies but here's how we did it...
First, we hung a picture of us in their brooder to help with imprinting
Actually, this is what has worked for us so far...
First and foremost, NO FAST MOVEMENTS!...We;re always careful to move very slow, our size is intimidating enough...
We then just laid our hands in there, one at a time, upside down and let them come to it...Within seconds they were climbing on it and then they both fell asleep in it!
After that, the hand always goes in slow and at the bottom of the cage...I also don't reach for them, I let them come to me and now they do almost regardless of how fast I move(although I still keep it slow)...
My personal concerns was hurting one of them as I have NEVER held a chick before these so my method was with that thought in mind...Good luck!!!!
>>>>PS. I just figured out the picture thing... so I'd like to introduce Thelma and Louise:
They are adorable!!!!!!
