Hi all, I need advice on what to add to the water of my chicks that are currently being shipped from a hatchery. I have Poultry Nutri-Drench that I am going to add to their water. The dosage on the bottle says 4 fl. oz/ per gallon for age 1-4 days, so 1 fl/ oz in a quart. Does this sound like a good starting dosage for newly shipped chicks? I would also like to give them probiotics but don't know how to add them. I have some ChickBoost, which has probiotics, vitamins and electrolytes. Should I put in two different waterers, one with NutriDrench and one with ChickBoost? Or should I buy the Save-a-Chick packets that have just probiotics, and combine that in the same waterer with the Nutri-Drench? Or maybe avoid overdoing the supplements and just do Nutri-Drench for the forst couple of days and then switch to ChickBoost? I don't want to overdo it, but want to give them all that they need. The chicks will be in transit for two days so I want to make sure they get the best supplement to get over shipping stress once they arrive tomorrow. Thank you so much for any advice !
