I found these ion the middle of poop on the poop board. Donning gloves, I washed off the PDZ granules. I thought it might be in digested plant matter of some kind, but it feels meat-like. Of note, coincidental or not, The hens have been on Amprolium feed for 2 days now since we lost a rooster to coccidia. Any ideas what the heck this is?!?!
