Bianca is only about 14 weeks old. Isn't that too young?? She's HUGE but still young. But she's laying down in "laying posture" a good bit in the run. She doesn't squat when I pet her back though.
I don't think it would mean eggs just yet, at 14 weeks.......But maybe she's older than you think? Usually you see that very intense squatting when you reach out to pet them.....Then you know for sure they're ready, and that they'll be laying soon.
Maybe look her over and see if anything is wrong. Check the vent area too.....
I can't find anything wrong. She's eating great, very active. I'm pretty sure of her age--she was hatched in an incubator by a client of mine and hatched around June 11.
