I don't want to give medication when it is not actually necessary but if you wait till you see symptoms of anything you have let it go too long so then how are you to know when to medicate if your chick is just standing by himself in the brooder with fluffed up feathers. I saw him, her, drink water and also saw him eat plain yogurt that I spooned on top of their starter. I don't want to wait till i lose my chicks before I do anything so is there some safety measures that I can take without harming my chicks. I had sent in another post earlier titled Worried about chick with other information. I wish I would be able to put a stop to anything before it gets ahold just to be safe! I feel like I should be doing something! They are still in the brooder and will be 4 weeks on Saturday! Thanks very much!
