I have 6 colors of leg bands so far. Each generation has a color and then each cross has a color so some have 2. It's a good thing I keep records or I would be confused. Some have zip ties some have poultry bands and some have both. My meat project is triple banded. 1 for each breed and 1 for the generation.
My husband thinks I'm crazy (he might be correct I did marry him). I explain to him that I could have an expensive hobby that never made any profit, but instead I have chickens. They pay for their feed and bedding plus put cash in my pocket. I see it as a win/win for him. I stay busy therefore out of his way AND I earn a bit of play money to take him on dates once a month. Plus the eggs and meat taste so amazing.
