My 3 baby chicks have seemed normal for the most part they are active they eat and drink they are about 1 week old. I saw 2 of them today make a poop that was very brown or like a dark orangeish brown, it was also watery, well, more like very loose but sticky. I started to get a bit scared. They don't seem like they have lost any appetite or thirst but i have been trying to remove the dark poos or cover them with a lot of shavings so that they don't walk in it or try to peck at it. I am worried, PLEASE HELP!
