So I just learned what sour crop is this last week when my silkie, about six weeks old, died after puking and having an enlarged crop. To make me feel better, I picked up four new chicks yesterday, all about six weeks old as well. They are all acting completely normal and very energetic but the frizzle has an enlarged pudgy crop just like the silkie did. If she has a sour crop then she had it before I got her but she is currently eating doumor 16% chick feed and drinking water with HydroHen supplement and Corid. I am going to suspend the use of Corid for now since that could be killing the good bacteria in her crop but I need to know what steps to take to fix her problem before it becomes serious. I will be broken if I lose my frizzle to this. What steps should I take with supplies that are easily obtainable? All help is appreciated !
