There was someone I was chatting with yesterday and he was telling me he uses fresh garlic to worm his chickens he said he chopped it up and puts it in their water he was also talking about how he used a different method to feed his chickens to increase the protein and build a disease resistance Barrier for his chickens he said he buy purina laying pellets and depending on how many chickens u have put a half scoop and for example if u have 10 chickens put 5 scoops of pellets and pour it in a bucket and fill it with water about a inch above the feed and let it set for two days and it will increase the protein and add probiotics from breaking down the feed don't know if it really works anyone have any thoughts
I have not come across any research yet to have pros for either garlic or ACV water. In fact, I found a couple sites that listed them as either ineffective or even have a toxic effect. I ordered Breda from a breeder that only used ACV and garlic as "natural wormers" for their stock. The two juvenile birds they shipped to me not only had respiratory issues, but were so riddled with bloody cocci and worms that my vet had to put one down. The breeder was adamant that they had healthy birds but my vet said the chicken he put down had been ill for quite a while for it not to respond to treatment and that if the conditions had been addressed with proper medication at the start the bird would've survived. Cocci and worms are easy to treat with proper medication and homeopathic remedies just aren't enough. Serious conditions need to be treated with serious medicine and not homemade doctoring JMHO. As for fermenting feed, the B vitamins break down and change properties. Read the article about why but don't ask me to find it now -- at the time it was fleeting research and I didn't bookmark it!
Poultryhelp.com updated their website for toxic plant listings and their effects on poultry. It's a personal thing how people feed/treat their chickens but I find the poultryhelp list helpful for myself.
