I wanted to see opinions from you guys on something I have been doing since my little's hatched. Every day, one a day, I put ACV and a couple drops of poly-vi-sol in their water. Occasionally I will pit electrolytes in it also. Since silkies are prone to wry neck and vitamin deficiencies, I didn't think it would hurt to give them a daily vitamin and ACV. I used poultry drench a couple of times when they were sick with the respiratory stuff, but I prefer the poly. Any suggestions or concerns with this?
