Today after the rain i let my hens go out in the yard and eat fresh cut grass,and when they all went back in the barn i went in with them to pet them,and try to talk my hens into laying more eggs.anyway,i was petting one of my birds and i noticed a lump on the back of her leg,right where the feathers start. The lump was huge!!! It felt almost like a cocaburr,but we dont have cocco burs growing within a mile of here!! it was as big around as my thumb,and im a big o boy lol It felt like it was under the skin,i couldnt see ,it is dark. ANYONE know anything about a lump on your hens?
