That second one looks more like the pink/orange of shed intestinal lining. Difficult to make out much in the first one other than a slight orange slime but to my mind I would expect much thicker darker red blood in poop indicating cocci. How old are the chicks? I find they shed a bit of intestinal lining anywhere from 5-12 weeks but usually around the 7weeks mark. I would keep an eye on them for signs of lethargy and being hunched but other wise I would not worry at this stage. That said I have a small bottle of Amprolium 9sold for pigeons) in my first aid kit should it be required..... it is probably out of date now and never been opened, but it is useful to have on hand ready to use if anyone shows symptoms...I would not consider that poop on it's own a symptom. Whilst I think poop can tell you a lot, there can be a wide variation that is still normal and it should be used as an indicator that thingrkt yups may not be good and to look for other signs, rather than a diagnostic in it's own right.
