In a matter of 4 days I have found out the chickens have mites, one chicken was severely attacked by most likely a dog, and now I have a chicken laying eggs with no shell. This is my first time raising chickens. I have six BO pullets and one BSL which are about 20 weeks old. Only the BSL is laying. She has laid 3 small intact eggs. Yesterday she laid an egg with no shell, not even with a membrane. Is this something to worry about or is it normal in the beginning? I am currently trying to nurse the injured chicken back to health. I am keeping her in a dog crate with food and water inside the run. She has small wound on her back and a puncture wound on her breast. I am treating it with vetericyn and Neosporin. She seem to be doing ok. She is only eating cooked eggs. I left some tuna in the crate but she wasn't a fan. When I went to add food this morning she snuck out of the crate and seem to enjoy foraging in the run until 2 other chickens started to bully her! Back in the crate she goes until she heals. But now I'm worried I'm going to have a hard time re-introducing her to the flock. And now the mites. I am on my way out to clean out the coop and run. I will be painting any unfinished wood in there. I didn't know to do that until the coop was built and the chickens were in it I will try dusting the chickens with permethrin dust and also spraying the run and coop with permethrin spray. I picked up ivermectin but not sure on the dosage to use. I also have sevin dust which I picked up to use as a last ditch effort if they are still around in a couple of weeks. I know there is some controversy with the sevin dust so I would rather not have to use it. Any advice or encouragement would be great! I have loved raise if these chickens so far but I'm going to go crazy if all this keeps up! The mites are the icing on the cake!
