So we originally thought it was coccidiosis but I looked all through coop and no bloody poop. Chic was worsening so fast. I get going through posts to try and find something. But then it was too late. Chic passed. I continued to look it over closely. Then I noticed a decent sized pocket near chest area. When back to reading again and now thinking it was crop bound. My question now is do I check the chicks every morning before they go out to free range? Do I put grit or oyster shell outside for them? My oldest is 3 mths then done a little from there. I do NOT want to go through this again.
