Whew I was worried when I saw that thing in there.
Yes these were the same breeding flock as last time. They're all my birds/ in laws birds that I'm taking care of. Five of the girls are 6 yrs old and the other 6 are all 9 months old.
If I don't have a vitamin supplement can I put apple cider vinegar in their water till I can go to the store tomorrow and get them some?
ACV isn't going to do what you need for them. I would just offer fresh clean water and get a vitamin supplement that contains vitamin b2 riboflavin when possible. Poultry Cell by rooster booster is a good one. If you can't get that then Polyvisol WITHOUT iron is a liquid baby vitamin that wouldn't also work well.
