Left the Babies

Josephine has left her babies. I googled how long a hen was supposed to stay with her chicks and it said 6-8 weeks. I’m not sure it has been that long and the chicks are still small. I hate this. I’m not sure the chicks are ready to be on their own. I guess they will have to figure it out. I do not like that they are so small and on their own. It makes me nervous for them.
