Cons: Not effective for many bacteria
Potentially carcinogenic
Stains everything
I don’t recommend this for your chickens as it is not a super effective product and only works on very few types of bacteria. I understand it has been “used for years”. We used to do bloodletting as a treatment for illness, too, but have moved on as we gained new and better knowledge. There are better products out there that work and don’t turn your chickens, or you, into a smurf.
This product works very well for sounds, but be warned.
It stains and is not able to be removed. If applied to the comb, chicken may shake their head and spray the blue solution all over your clothes and skin.
Cons: Wear gloves or it will stain you for a while
This is a necessity for anyone's emergency/chicken medical kit. If you have a would that needs healing it helps keep other hens from repeatedly pecking the affected spot. It can be use just for so many things. Get a bottle you won't regret it.
