I recently purchase 5 hens from a friend. How long will it take them to acclimate to their new home and recover from the stress of moving before they begin laying? My 7 year old daughter is so disappointed that she hasn't found an egg yet even though I have told her the chickens are still adjusting. It has only been 3 days, but I wanted to try and give her a better idea of when the girls might produce. The breeds are wyandotte, Orpington, Australorpe. Thanks so much!
