Don't know what to give my chicken as a home remedy as I am very new to chickens. I have started with apple cider vinegar in the water to the chickens. What else can I give them to help that I may have in my home?
You say that your chickens are sick and sneezing, but you haven't given me any symptoms. A sneezing chicken could be as a result of the bedding you are using and it is just causing an irritation.
However, if your sick chicken has other symptoms, such as breathing difficulties, gummy eyes, gasping, dirty vents etc. then we know what we are dealing with.
I suggest that you check to see that your chickens are not directly in a draught. They like to be housed in protected conditions, but still with good ventilation.
Separate the sick ones from the rest of the flock. If they have breathing difficulties you can either spray a fine mist of camphor over the birds, or place a few drops of camphor oil into each nostril. If you don't have camphor oil at home you can use hydrogen peroxide instead. Dilute it 50:50 and place a few drops into the nostrils.
Then fast your chickens for a day, but giving them clean drinking water with the cider vinegar. Make sure that you use the right cider vinegar. It must contain the mother culture. This is the only cider vinegar that has healing properties. You can also add a teaspoon of active Manuka honey to the water if you have it.
The day after the fast, feed them a laxative diet of cod liver oil, spinach and other greens, chopped garlic and a small onion. If you don't have cod liver oil you can give them a warm mash mixed with molasses, cider vinegar, spinach, garlic and onion.
If you have sage and/or aloe vera in your garden/house you can add this to the feed as well.
After that, resume your normal feeding pattern, adding chopped cooked egg yolks and some grated apple to the daily feeds until chickens recover and assess.
Unfortunately, respiratory problems in chickens can account for a whole number of diseases and illnesses. This is why it is difficult to make a judgement based on what little you have told me. However, 9 times out of 10 it is just a common cold, although there are times that chickens can die of such things, just as humans can from the flu. So all precautions have to be taken.
