My babies are due to arrive this coming week through My Pet Chicken. I bought a bottle of Poultry Nutri-Drench for them since I've read that it's good after shipping. My question is this... should I put this in the water and just let them drink it or should I just put a wee bit on each beak? Not really sure what to do with it. The directions say 4oz per gallon of water but I've seen on here where some people are just doing drops on a beak. Thanks in advance for any help.
