Approach I like the best with older chicks it to confine them near the broody hen so she can hear them from close range without causing them harm. Heat lamp. food and water provided for chicks. If chicks more than a day old, then it takes about 2 days for them to be interested in hen. Hen requires about same amount time. They learn each others voices. Then introduce chicks immediately before everyone goes to sleep for the night. Check when lights come on to make certain hen and chicks bonded, if not then do as before for another day and repeat.@centrarchid How do you do it? My broody had 4 chicks and I wanted her to accept some day old hatchery chicks, but she rejected them so I ended taking them all away. I noticed the stre-bought hatchery Australorps aren't as quick or smart as the other chicks. The Australorps just stand around a lot. Two days later, without any chicks, she is interested in the rejected chicks. I am tempted to see if she would take them in. Has anyone done something crazy like this?
Do not attempt with hen with very old chicks or that has not been brooding eggs for at least 18 days. Outside that range makes for very iffy results.
Somewhere I detailed process much better on this site.
