Good Mama sounds extraordinary and very dedicated.I have had several lonely only pullets that went in the nest box with chicken mom when she laid. Around 10 weeks until spring.
I have a turkey hen, good Mama, whose eggs didn't hatch for a couple years. I give her chicks for 2 years that stayed with her until she goes broody the next spring.. they were pullets.
This spring she got 3 chicks and 4 poults that others were ignoring. One turkey hen, who hatched the poults moved in after a couple weeks and took over her poults. One chick was a pullet and a mink got her. The others are cockerels and she is still taking care of them at 15 weeks. The other turkey hen is not pleased that they try to sit by her. Good Mama has to defend them. Not sure how the mink managed it. I'm not sure what is going to happen when I harvest one or both of her cockerels.![]()
