I have two female pekins and I noticed two eggs the past two days (one a day) and they just turned 19 weeks old today. I am not sure if just one is laying or if BOTH of them is laying. Do I switch to layer or should I just add a supplement until I know they are both laying? I don't want to hurt them in anyway by change their food. Also, I am 98% sure I have two female. I ordered females from Ideal but Quinn is super loud and very obviously FEMALE whereas Olivia is much more quiet. Her quack IS different but not so obvious as I would have been told it would be. I've tried picking her up or separating her from Quinn and she is so silent or just wiggles to get away so I can't hear a difference. There are no drake feathers and at 19 weeks I haven't noticed any attempts at mating.... IF Olivia does happen to be a drake...........can I still feed them layer or should I just be supplementing?
