Maybe she's on her way to going broody.She’s been getting on it and getting off like a freak! When I tried to look under her she just ran off. It’s dark out now and she’s still roosting so I don’t know what’s up? She lays very early, 6-7 am, so it was an odd behavior for her. I know that sapphy hens don’t typically brood but she’s an exception. Normally I wouldn’t care but I’ve been trying to expand my flock before the colder months and my incubator is currently being used for coturnix so I can’t just hatch them unfortunatelyAny tips on helping her are appreciated!
Everyone hates advice like this, but here it is: be patient, leave her alone, and see what happens. It certainly sounds like she's pre-broody, if that's a term. I'm a bit afraid that if you keep peaking under her on the nest and all that she'll just freak, and not go broody.
