Had to dust off my chemistry degree to tend to Navi. The treatments for impacted crop were not working, so we moved on to treatments for sour crop, thinking that she has a fungal infection in her crop. I’m still following the advice in “The Chicken Health Handbook” by Gail Damerow. For sour crop, she recommends a flush, then treatment with Copper Sulfate. To make the Copper Sulfate drinking solution, first you have to make a stock solution, then add a little of the stock solution to a gallon of water. This is where my chemistry neurons had to be dusted off, and frankly I had to consult with my chemist Mom, because inorganic chemistry has never been my strong point. I made the stock solution and drinking water, which promptly turned cloudy and a little while later had precipitates at the bottom.

Copper Sulfate solution should be clear. I figured out that it was probably that I used softened water from the sink, so remade both solutions using Reverse Osmosis water. Ah, a clear solution. My Mom hypothesizes that the precipitate was probably Copper Chloride Hydrate. I could have tested the precipitate, but I had already used the solution for a root killer in the yard, pouring it on poison ivy and saw briar stems. Copper Sulfate is a fungicide and a root killer.

We’ll see if this treatment helps Navi. She is in isolation, but I’m glad I took my Dad’s advice because the isolation ward is at a good height, I can lean in, and it is plenty big for one chicken. Navi can see the other chickens, has a roost, food, water, and even a small foot bath. Although with her medicated water, she only gets a frozen water bottle on a plate so she doesn’t drink foot water. Ugh.
