Hey there! My three barred rock hens are now of egg laying age but have not laid yet. Every morning, I get up and let them out. They want to be let out. I take the younger chicks and put them in the run while the adults graze the yard. I am not seeing indications that they are getting ready to lay. Am I letting them out too early? Do I need to keep them in three coop longer? Should I only let them out in the evenings before dark? I'm new to this so any help would be appreciated. Also, I live in Florida so keeping them in later would mean they would get awfully warm.
