A WEEK?!? Here I was expecting another 2-4 week wait! Wow, if she follows the example ya'lls chickens have set, I'll have my full quota of eggs in no time!
None of mine squatted. Not before starting to lay, not after. They don't sing the egg song either. Right now, they are all on hiatus, at least one doing a partial molt.
All of mine had a 10-14 day delay before laying onset except for 1 bird, who still isn't laying but showing other behaviors typical of a bird close to lay.
