One week ago my 10 assorted chicks got delivered from Meyer Hatchery via the post office (2days old). I also went to my local feed store Runnings and purchased 6 Turkey chicks (about 1 wk old). All seemed to be going well the first day I noticed one of the Turkeys had pastey butt so warm wet paper towel cleaned and ready to return to feathered friends. The turkeys were a bit bigger and there was some pecking but nothing concerning...Then Friday morning one chick dead. I hadn't noticed anything wrong at that point assumed shipping stress or crowding at night. Then another chick started acting wierd not active but not panting or anything died Sunday afternoon another chick same thing checked for pastey butt clean, checked food realized DH bought layer crumble went through threads here and came up maybe food upset kidneys due to adult calcium levels or maybe corccodosis. Another chick started acting lethargic dead in the morning. Bought chick feed and started treating for corccodosis Monday morning. This morning one week after getting chicks and Turkey chick is dead and 4 of remaining seem to have white messy butts. I am at a loss I have never had this issue before I have owned chickens since i was in 3rd grade raised 4 sets of chicks one hatched myself. Pic attached of setup switched from pine shavings to newspaper to clean more frequently and monitor easier. Also Turkey butt with issue. Please some direction as what to do I am heartbroken and worried about passsing something on to my adult hens that are outside. Also we were planning on eating our Turkeys so need to know human implications for diseases if possible.
