I have introduced new members to a flock in the past but had a sad turn of events this time. I had 5 layers and pickup 10 chicks and raising them just fine. My old chicken tractor was falling apart I was in the process of building a new coop and run to move the old birds and new ones into. Before I finished the new coop my 2 Brittanys managed to get the screen open enough to flush all but one of the older hens out to there death. The hen that didn't flush out of the tractor was on the bottom of the pecking order. The chicken I have left is very shy. I have shown the the older chicken the babies and she has showen no interest and walked away. My question Do I still need to wait until the chicks close to her size before I introduce them.
