My chickens have been acting strangely for a while now, not laying eggs, having egg whites in their poop, and passing crushed eggshells and other strange objects. But THIS is completely new. This has not happened before and I really don't know what to do. I only have six chickens as of now, so losing any of them would be a tragedy to me. I've brought them to the vet and all they did was give us some antibiotics and said that they didn't know what was wrong with them. This THING is only an addition to the series of problems I've been having, and I've just kinda been learning about this as I go, looking up stuff when necessary. So any tips would be helpful.
