My muscovy duck is acting weird. She still isnt laying and about a month ago she lost her sister and boyfriend to a tragic accident.she has been alone ever since. We are trying to get her more friends but neighbors who have them are having problems catching them. Meanwhile she got use to the chickens and hangs out with them a lot. We have a duck coop where she stays by her self at night.about a week ago she started to stay in a coop more and just lays in her nesting box. But doesnt lay any eggs. I am wondering whats wrong with her. She dosnt eat her corn and seeds like she use to.and only goes for a swim in her tub very little. Is she just bored or is it too hot. Its been near 80 lately, she and the chickens hang out a lot under a cedar tree getting dust baths and she sleeps there too during the day.should i be concerned?
