Our 5 day old chick was perfectly healthy up until yesterday morning. then he started getting lethargic and now he has yellow diarrhea, which just sticks all to him. I keep cleaning him off. i read somewhere to open up a capsule of a probiotic pill and mix it with 2 cups of warm water. i did that and that's what i'm giving all the chicks to drink. i have him in a separate part of the brooder away from the others. i read that yogurt is good to give them. should i just get plain yogurt or what?
what else can i do? he just cries all the time.
