Alright, here's the scoop. The 'Scovies bunk in with the chickens at night and sometimes we change the water every other day, depending upon how dirty it is. The ducks are usually let out after they get some breakfast with the flock. There are only two. After that, we let them free-range for the remaining morning and afternoon and let the chickens out to join them a few hours before dusk. Then everyone gets locked up for the night. My parents are responsible for taking care of everyone in the morning on weekdays, as I have to get ready for school. They really aren't responsible for the extra care, that would be my thing. This is everyone's first day on ACV and I made sure the ducks didn't get any today, just in case. I don't know if it's bad for them and they may go for a drink right away, before my parents stop them, first thing in the morning when I'm not there to change around my planning. Will this cause harm for ducks? If so, I'll make sure the chickens only get the ACV on weekends, when I'm in charge of things outside. I'm going to bed. I'll check in with any answers tomorrow. Thank you, anyone, in advance!
