I started with my babies on the first day, offering wet mash in my hands. By day 3, when the trap door opened they would jump in my hands & arms to get to the food! I can pick up all but 3 of the 15 by reaching in from up top, but all will come & get food from my hand if offered. I think part of it is personality, as there are a few that jump up to be held, some I can pick up without a fight although won’t jump up to me unless I have food, and the last 3 that sqwak bloody murder if I hold them (although they eventually calm down, I don’t force the holding for a long time.) My shortest goal is to be able to handle all of them if necessary. My biggest goal is to have a flock of cuddles. I’ll settle for somewhere between the two.
If I could do it again I would probably wear them in a scarf or pocket, one or two at a time when they are just a few days old. They will snuggle when they are brand new. I WOULD NOT do this if they were hatched by a broody.
