This is the first time I’ve ever had chicks. We are doing it through 4 H Chick Chain. I’m not sure what it’s crop should even feel like. It doesn’t make any noise at all and I haven’t observed it poop since discovering the problem today. But in general, there is no dry poop. There has been some diarrhea amongst the 4. I have been giving Corid in the water for the past 2 days and had been adding ACV to the water prior to that. They have had nothing besides crumbles, so I haven’t been giving grit. Yesterday, I discovered that the waterer was faulty and had completely leaked out and wet the bedding (they are on puppy pads), so they had been like that for a little less than 24 hours. I did smell an ammonia smell when I discovered this issue, but I would think they would have all been in distress instead of just one. And of course I changed everything out immediately.
