All right, I've got 1 RIR hen who has been sitting in the same nesting box for about 3 days now. I know she's not moving because two of the other girls usually lay in that same box and have now been forced to lay in a neighboring nesting box. She looks flattened out and keeps an eye on me when I feed them, change water, add treats and open/close the coop - but she doesn't make any noise or get up. This is only my 2nd year raising chickens so my inexperience causes me to question just about everything they do. I've haven't had other hens act like this, so has she gone broody? (She's almost 1 year old, btw).
Here's my true ignorance...I have no rooster. Is it even possible for her eggs to hatch without a rooster around?!
If not...how long will she sit on them before she realizes nothing's going to happen?
The other girls don't seem to bother her - they go free range during the day, and are perched on their roost at night - so do I need to seperate her if they're all still getting along?
