So I have 5 chicks under my broody hen. This morning I went down to check on everyone and the little polish was out at the edge of the coop...cold and lifeless. I thought it was dead, so I scooped it up, looked it over, and checked on everyone else. While doing that I felt a tiny movement and thought I saw a gasp from the corner of my eye. My heart skipped a beat and I cupped the chick in my hands and started to warm it with my breath. Sure enough the chick gasped again, so I ran inside and continued to warm it in my hands. After it started to breath regularly I stuck it down my shirt to give it direct body heat. I had to go to work, so I drove with the tiny chick in my hand in front of the heater. By the time I got there it was chirping at me and standing! By the time I got it home it was chirping LOUD and quieted down once it got back under mama. Now I need some help. I didn't have any food with me at work, but when I tried to give it egg it wasn't interested in food. It's crop was noticeable but soft, and about 10 minutes after it took a drink, I put it down and it shook its head causing the water to come back up. It had runny poop, as if it wasn't eating well, and is smaller than the others. I also felt like it had a fermented/stinky smell coming from its mouth but its very hard to tell with a runty 4-5 day old bantam polish chick. It is also sneezing occasionally, but those are the only symptoms. SO, any idea what's going on? I feel like its not eating well, but how do I get it to eat? Can chicks this young get sour crop? Could the fact that its body was shutting down be why its poop was weird and it wasn't voraciously eating? Here's the baby I'm trying to save. If it makes it, I'll have to name it Lucky or something.
