I have been raising a flock of Mallards for last few months and they have all migrated except for a single female. She has never made the loud loney call till recent events and before was fairly quiet. We bring her in at night and no longer let her graze during day, instead pin her in her coup. I try to sit with her as often as I can but obviously will be impossible all the time. Is it cruel to leave her alone? We ordered a diaper and hope having her inside with us often will be one solution. I think getting a companion duck would be better option but don't know if needed. Please community, help ease my mind that she is ok in a protected enclosure all alone sometimes, and can adapt to being indoors with us most of the time.
