I have too, but none of our bigger ladies have ever increased or restarted production from hearing chicks. It's really food for thought. Maybe bantam chickens are more apt to do so?? My other two ladies haven't changed or increased/decreased egg production. Just this one hen.
I forgot to add that I cracked the egg and it's normal and yes I know it's hers they vary in their shades and I can tell who's is who's because I only have 3 currently. Hers is also slightly different in shape. (I'm hoping for pullets and not a all rooster year and that's happened to us before.)
I feel dumb for even asking this but my mlle fleur female reached point of lay, laid two eggs and stopped.(9/11 of 2022)
She's laid twice this week. She can hear the chicks I currently have but cannot see them. Is it possible the noise has kicked up her hormones and got her laying again??
