What happened to the first one? Similar symptoms, or something totally different? If it was under similar circumstances, there may be a hidden problem with your birds. I don't know that a poisonous spider can make them sick when ingested. I thought the venom had to go into the bloodstream, but I could be wrong, Google it and find out.I only have a small flock of four! Have only owned chickens for alittle over 2 months now and already lost one if she passes this will make 2! Maybe im not a good chicken person i take losses to personally!
You are not a bad chicken person. The thing with chickens is, it's kind of a high learning curve. Chickens die. Sometimes for no apparent reason, sometimes due to inexperienced management, sometimes due to predators. These are just a few reasons. There are many more. Don't give up. Keep learning.
As I said, there's always a reason. I'm glad your coop didn't burn down with that shorted out lamp.Its not that i am sure you are doing fine. I lost 7 good heathy chicks all in one day for no reason and after that i didnt want anymore because i blamed it on myself. It was a bad wire that shirted the heat lamp, that killed them. I do have more now a small flock or 8 turkeys (counting the new babies). Problems will come and its hard, sometimes what can happen is that they eat a bug that is bad. Thats what happened to my little Snow. She is fine now but she did scare us because she acted like that for some time.
