My dad gave me a laying hen. It layed fine for two weeks then stopped. So he brings me another one to switch out. 30 minutes after he puts the non laying hen in a cage in his car, it lays an egg. So both of them lay for about a week, then both stop. What am I doing wrong? I have no clue. why would they lay for him and not me? Also-both times the egg shell color changes. They go from brown to an off white ivory cream color. Anyone know what I'm doing wrong? I'm about to give up.
