I am brand new to raising chickens. We have 16 chicks about 5-6 weeks old. They are all acting healthy and happy. We let them out of their brooder for a couple hours a day to free range in the yard. A few of their poops look funny though. One in particular has a white runny poop! I have given them one dose of a dewormer in the water, it was Wazine, about a teaspoon in a quart of water. I also have them on medicated feed. I also notice some other runny, yellowish brown poop and some with a very little red in it, not sure if it's blood or not?. Please help Thank you!
