@The BlanchRanch Those symptoms I've never had in my chickens. You can search out some threads here on BYC and prepare to dig in follow a couple six threads to get a single line of common factors, symptoms, and common treatments. I'm thinking maybe some Duramycin for a respiratory? Or Tylan? IDK without researching it myself. Sorry I couldn't be of more help. It's helpless feeling sometimes. But search, search search on here. You may just find it. The eggs without shells maybe a seperate issue all together. Or just a part of the infection itself...if that's what it is.
Good luck.
