Hello everyone. I am new to my ducks, but my khaki just started laying and one of her first few eggs was really big, and when I cracked it open there were two yolks, is this unusual? Also, is it better if I have two females to live with my one rouen male? I live in oklahoma where the winters are pretty unpredictable but can get super cold. My ducks live in my backyard but I have a tiny coop that they really dont use, but she is laying her eggs in there. If I had two females would they be likely to share the nesting box or are they territorial?
