Hi everyone. My husband and I are new to the backyard chicken raising and thought having a few chickens would be good for the kids. Well, we have some problems. First, we purchased all the hens at the same time from the same feed store. Everything was going great. The ladies are about 5 months old now and we were getting ready for the excitment of eggs. Well, one day out of the blue with no signs or symptoms... dead hen. No predators, no discharge from the nose, mouth, etc. Nothing visable from looking her over as to what killed her. We figured perhaps it was genetic and 1 out of 10 seemed like we did okay. We were already using DE and figured this was controlling any pest problems. (There are wild peacocks nearby too, not sure if this is important or not, I will leave it to you.) About a week later, another dead hen. Same issue, no symptoms. Sunday night everyone was fine, upright, eating and drinking no lethary, etc... next morning, dead in the coop. So at this point we started doing some research and called around. It was brought to our attention that we should worm them and check them for mites/lice. I noticed that my Poland was very pale around the eyes so I brought her in the house. We wormed all hens with Wazine. I found small, straw colored bugs on the Poland. We dusted the chickens with DE, dusted the coop with DE originally and then Savin Dust. We blocked the coop so they could not get back into it so we could treat the wood with Savin dust and DE. Yesterday the Poland looked much better, good color, good attitude, eating and drinking (never stopped or seemed lethargic though she did have loose poop). I put her back outside because she seemed sad in the house. Today I put a fan on them (I figured because they were sick they were having a hard time regulating their body temps, they were all panting.) Fan and shade seemed to stop the panting as well as some frozen blueberries. Well, tonight the Poland is pale again. I have brought her back in the house. I noticed the same strawcolored bugs and also a red larger bug... What is going on here? What do I need to do now? Thanks everyone!
