I have one girl who was wandering with her sisters earlier and now sitting in a nest box. How long does it take to lay an egg? These are 17 or 18 week old sexlinks. She's been in it about 20 mins now, preening the shavings and placing them around her. She's laying on the tester egg and moving it with her beak from time to time as well. Hoping she's going to push an egg out then go wander away. She's left us two so far ... Little ones, but two perfect little eggs none the less. Tell me she's just getting things down and not broody already?!?!?
