Blood in poo? Or intestinal lining shedding?

[goodwiab]

Hi! I have six 8-week-old chicks that are still sleeping in the nest box and a big pile (I also have two three and 5-year-old hens that roost and I think they're still too scared to join right now). I have been finding one or two poops each morning in the nest bedding such as one pictured. All of the chicks are acting completely normal good feathers good eating and drinking etc. wondering if I should be concerned or is this just normal intestinal lining shedding? Trying to figure out which one is doing it but I'm wondering if they're all just kind of rotating. Thank you for any and all help!

It would not hurt to start some Corid in the water, 2 tsp of the liquid or 1.5 tsp of the powder per gallon of water for 5 days, just in case they are getting coccidiosis from the older birds. They are at that age where it could happen, and Corid is safe for all of the birds.
