Well it depends. When I saw yours they didn't look very close to laying age(no offense) so maybe around 24 weeks. See nugget in that big pic? Well that was right before started laying, their face will look similar. Let me know when the first egg comes!
Hmmmmm when do you think my chickens will lay??? There 19 weeks.....maybe they will lay at 24 weeks that's a good age....when did your chickens start laying????
