Have a Barred Rock hen broody, don't know how many she is setting on, she has been on the nest since last friday 4/28, I have tried to give her water and food , but she will not take either, is this normal? the other hens will not use the hen boxes to lay, they have found a old nest box, on the other side of the coop to use. I have noticed she will allow me to pet(smooth) her feathers, and she makes a funny sound when I do this, and it is not a upset sound. How long until she hatches them? thanks for any info!
