Hard to believe older experienced Chicken keepers don't know...what bumblefoot is!! I am meeting so many more people around who "used to raise chickens all my life" and they don't know what it is. This surprised me that they didn't notice any problem with chicken health in 30+ years of chicken raising! I watch my flock and I notice if something is off. Might take me a day or two to figure out what is wrong but I usually find it fast. Sorry for the negative tone. I was just amazed at the fact of what I am finding out by talking to "old timer" or "experienced" chicken raisers/farmers.
