4.5 week black australorp with unusual poops

[my beautiful girls]

Lily has been having initial poops like this in the mornings. They were all treated with corid 2 weeks ago. She acts normal and gaining weight. Is this intestinal shedding? Other poops during day are good. Any advice? Other chicks have some shedding but not with the white mucus poop.
