I was watching my chicks last night and one of them pooped a very watery poop with some orange / red in it ... I snapped a photo for all of the experts out there... and another one of a poop that was in the brooder this morning .... They seem to be acting fine eating, drinking, jumping, playing etc..... Should I be concerned??? They are 3 1/2 weeks old have been eating medicated chick starter and are now on paper as the shavings I had proved to be too dusty for them and were making them sneeze..... I have been putting apple cider vinegar in their water and have given them yoghurt and garlic a few times..... Photo 1 Immediately after pooping..... last night .... Photo 2 - Found this morning... dried a bit but you can see the ring from the dried water ...... Thanks for your help!!!!
