I just gave some antibiotics to my chickens in all their watering places....I also have a potbelly pig and put it in her water because they use hers too. I have a pregnant goat and did not put any in her water. I'm not sure if they will get the right amount of medication of they end up drinking the goat water because they don't like the medicated water. Also....do I dump each days water out of the waterer and put in new water with new medication each day or do I leave what is there and replenish it as I usually do? I appreciate your help....I am new to this.
