I will have had my chickens 20 weeks on Monday the 24th of August. They were over a week old when I got them. Do some breeds take longer to start laying? No eggs yet. I have 5 hens and a rooster. 3 Rhode Island Reds and Buff Orpingtons. They kick all the chopped straw out of the nest boxes into the coop. My rooster has been "courting" them for weeks now. I check the whole chicken yard, the coop and the boxes 2x daily. They are empty save the 2 fake brown eggs I put in there. I am in N Florida and it has been rather hot daily and down into the 70s at night. There is plenty of ventilation and the yard is under trees and has a roof. They are out by our little lake which often has a nice breeze blowing. Am I just being impatient? Lol
