I picked up two new Golden Comet hens last week, giving me four Gold Comet hens in total, the extent of my brood, and after one week, one of the two new hens has yet to lay a single egg. The other hen laid an egg two hours after her arrival, and has laid an egg every day since. The age of both hens is 13 months. How long should I give her to lay before I need to consider other options for her? Can anyone hazard a guess why there has been an issue so far--especially since she has tried establishing herself as the dominant hen among the four?
