Costraván, nettles, and Chicken weed are the principal herbs used for feeding purposes.
Nettles are used either raw or boiled and are cut small and mixed with meal or pollard. They are very fattening for turkeys especially.
Costravan grows on ditches and meadows and is picked by slipping a knife under the root. It is cut small by means of a cutter and mixed with meal and given to fowl. It helps to make hens lay well as there is iron in it.
Chicken weed is treated in the same way as costravan and is great feeding for pigs if mixed with meal or pollard.
