Ok so I have had about 4 birds of all ages and sizes just die this last week... All had found in their crops , not skinny, no mites, no lice, they have all had fresh food , fresh water and tons of scraps and veggies.. They have all been acting normal , poo normal, roosting, eating and laying... so i'm kinda baffled here.. I hate to use any kind of antibiotics but I am ready to now... Any ideas ?????
