Hello I was tending to a sick listless pullet from my flock (4 months old) for the past few days that roam freely around the house and in the woods some days. The chick was not eating but was drinking a bit the crop was not swollen or have any signs of being impacted., green bile poop (likely due to not eating) no noticeable parasites either. The other 7 pullets seem healthy. I had been giving the chick some antibiotic vitamin water for about 2 of those days with no improvement. Anyways this morning i found the chicken dead and i did a necropsy that focused on the gizzard (I was assuming it ate a piece of plastic that I found in the coop but when I opened the Gizzard i found a bunch of seeds approx the size of popcorn seeds . The chicken was in quarantine for about 3 days and never came out of the pen for another couple days so i would assume the seeds were in there at least 4 days and never made it through the chickens gizzard for some reason.. I was suprised that this size seed would not go through the chicken and have read about people feeding there chicks popcorn kernels which are about the same size. the only other thing i can think of was that these seeds may have been poison to the chick. Any input would be helpful. I will attach a pic of the seeds that were in the crop and in the pic it is approx. half of the seeds that were in the crop.
