Wow - I just learned a lot, will be checking out the "sticky". I am fortunate, when I visited my customer with chickens and helped her set up the waterer I built her, I was wearing my pond shoes. Which get exposed to ponds, and periodic bleach dunkings, but never ever worn in my yard. Particularly fortunate, I spotted a dead fluffy pullet (some fancy breed or other) in her quarantine pen.
I had been thinking about borrowing a roo from her if one of my hens goes broody, I have cancelled that thought. What about getting some fertile eggs from her if I end up with a broody hen? Any advice on this? She lives in the country, and she is pushing 70, but overall her chickens are healthy. Predators are the biggest problem. She gets her stock from the feed store or hatches them out herself.
