Also, I have read that a lemon slice in the water will aid in reducing bacteria in the water. I live in Florida where it is hot all the time and I want to make sure that the chickens don't get sick due to the heat and bacteria growth in the water.
The lemon slice would have the same effect on calcium. Lemon and Vinegar are both acidic.
This is the recipe i use for disinfecting things like milk containers or my seed sprouting trays. I use it where a bacteria or fermentation buildup needs to be wiped out before the dishes can be used again. It's considered safe enough for humans that i can use the containers right away after just rinsing.
However,
I have never used it on anything chicken. I haven't heard of anyone having to get the bleach out of the tap water before watering the chickens, so it should be safe. If i am wrong someone correct me quickly please.
To use 'Bleach Disinfecting Spray". First wash out your waterier. Use a brush if there is any 'slime' in the waterier, rinse. Then spray the bleach disinfectant on all surfaces. Let set a few minutes, then rinse all the bleach back off before filling the waterier with clean fresh water for the chickens.
Don't use a ready made commercially sold bleach spray product. Use the disinfectant recipe below in a spray bottle. Oh, use non-scented bleach, trust me scented bleach can leave a taste that's hard to get rid of. To get rid of the taste you have to allow the utensil to 'air' to make the taste go away. Nothing quite like fake lemon flavored alfalfa sprouts. Uuugh...
Bleach to water ratio for disinfectant (use old style non-concentrated bleach):
1/2 Cup Bleach per Gallon of water
or
1 1/2 teaspoons bleach per cup of water
Put needed amount of bleach for recipe in a spray bottle, add water. Attach spray bottle top. Shake. Label bottle. Ready for use.
