My 4 buff orps are 7 days old today. Have been happy abd healthy. Today i noticed 2 very loose stools in the brooder, cant tell yet from who. Theyve been on nothing but medicated feed, and were taking water with vitamins and electrolytes (1/4 tsp per gallon) until 2 days ago. Should i be concerned or doing anything? All are eating drinking and acting totally normal. Temp is now down to about 80-85 on the warm end of the brooder and 70-75 of the cool end . They have been busy practicinf perching and testing their wings. Are loose stools normal some times?
