Are these poos normal for chicks? Help!!

Hi! I am pretty new to keeping chickens & have recently been given 2 chicks from my daughters school. The chicks are now 5 weeks old and doing really well, except for their poos!! Recently one or two of thier poos a day have what looks like a red mucus / jelly like substance in it. The lady who i bought my POL girls from thought it could be coccidiosis and I have been treating them with the coxid she gave me for the last 7 days.
However, looking at your chicken poo pics, thier poos look very much like those with intestinal lining, but I was wondering if they would be having these sort of poos on a regular basis?
Other than these poos they are fine, eating and drinking well and really lively!!
Any help or advice that can be given would be greatly appreciated!!

Hi! Thank you very much for replying to me.
We had the chicks at 10 days old & I put them on a medicated chick crumb with the anticoccidiostat. The poos that they have are all fine, except literally an odd one or two with this red mucus in it - for about the last 10 days. Being new to keeping chicks I really want to make sure they're all ok !!
I think you are right & the pics of the coccidiosis poos are much more bright red compared to my chicks' which are far more like the intestinal lining pic.
Do you know if they have these sorts of poos often?
I will take them off the coxiod & put them back on thier medicated crumb & thank you again

Hi! As a first timer with chicks, it is very worrying!!
To know that others have experienced the same thing, such as yourself with your chicks,  and it is nothing serious is really reassuring.
Thank you so much for replying to me and helping to put my mind at rest - very much appreciated!!!
