We recently got 6 chicks who were about 6 weeks old. We put them outside about a week ago. They've had some scraps but we cut out all the scraps a few days ago. They are eating chick starter and get grit and plenty of fresh water, and they have a small yard to roam in with grass, bugs and other things to scratch for. A couple of days ago, two of our chickens died within 24 hours of each other. The remaining chicks looked fine, and that's when we went back to basics, added a three walls around the coop for a little more warmth, and cut out all scraps completely. This morning, all four remaining chicks looked fine. We just returned home and one of the chicks was close to death. My DH put it out of its misery because it looked like it was going to go fast and he didn't want it to suffer any longer. We're new to this and have no idea what's going on. Why are they dying all of a sudden? Could there be a disease they picked up? Something they ate? I am so upset at the fact that our chickens are dying right and left and don't know what to do. I don't know what to look for with their poop, either. I saw a page with chicken poop on it and I haven't seen anything out of the ordinary, but they spill a lot of stuff in there too so I'm not really sure what I'm looking at. Any advice would be very much appreciated. I feel like I have the touch of death with these little guys.
