I have had ducks for about a year now and 5 out of my 6 ducks stay together my female Muscovy likes to be alone. She doesn't even let the boys near her she Is afraid but today I looked out and the boys were right next to her while she was laying down. She has a pen but gets out but I put her in a night and It rained recently but anyways I scared her by accident and she sat on the fence and she pooped. Normal right lol I know that's normal but her poop was really dark brown and a little liquidly I don't know if its normal but im a little concerned please let me know what I should do. and she is about 1 year maybe 1 1/2 years old
