I've got 3 two week old chicks and one that's 2 1/2. Wyandotte, Leghorn, RIRed, Brahma. One of them has very soft, almost diarreah poop (does not seem bloody). I'm not sure which one and I think it is just one judging by the amount and distribution of more normal looking stuff.
They are all drinking and eating. They are in a 5' x 2' x 2' cardboard box with a red heat lamp at about 80-85° in the basement (under a window for some natual light as well) They are eating medicated starter crumbles. Drinking plain water with a TBSP cider vinegar per gal and a separate container of water with sav a chick probiotic and electrolyte.
Is this soft poo a problem? If so what should be done?
