She sure sounds like a typical broody. They seem to get in a Zone, a Broody Buzz, like some sort of deep Zen meditation. Their combs can look pale, but they should still be alert when you approach them closely, growl a bit or more at you, try to peck you when you reach towards them. Some hens are more fierce than others. With some you need to wear protective gloves, I've had others who were more mild. But you should still be able to see a difference between the Broody Buzz and a weak, ailing apathetic hen.
When is she due to hatch? I have a hen on my patio whose eggs are due tomorrow. Last night I held one of her eggs to my ear & heard the chick cheeping & could feel it moving in the shell.
I have another hen that began setting 3 duck eggs I placed under her last Sun. This Sun I will add 3 chicken eggs to her clutch. Then if all goes well in 3 weeks more she should hatch a mixed family of ducklings & chickies!! That's double
!! And they just happen to be due to hatch on ... Mothers' Day !!!
