I have a baby Serama chick that is only 4 days old. At the beginning of today, I noticed her standing apart from the others and falling asleep standing up until her head rested on the bottom of the tote. Around midday I noticed bloody, watery stool. At this time she started to sleep with her wings ruffled away from her body, not trying to sleep with the other 6 chicks. I looked online and found out that coccidiosis can cause these symptoms, but I wasn't completely sure because she eats normally and drinks regularly. She's not as active as the other chicks, either. Just now, she pooped and it was the right color and pretty solid but with a lot of water. Should I go ahead and worm her and the rest of the chicks as well since I don't believe I bought medicated feed? I'm worried about her, she was the only brown one out of the bunch and I'm already partial to her!!!
