Hi, Now that my chickens are around 17 weeks old and the golf balls are in place I am wondering what else I could do to give them a good start to laying eggs. Right now they have the freedom to leave the coop at any time in the morning and enter at any time during the day to go back inside for bed time. When they go in for the night they go straight up the ladder and cuddle themselves to sleep. Do you recommend I lock them in until a certain time in the morning? In which case they would be forced to hang around the nest boxes in the coop? Or will this come naturally? Do I have to turn on the light after they come in at night and then shut the hatch for more night activity? Also should I feed them oyster shells like I've read in other posts? Thanks!!
