Crop needles are used to administer emergency first aid treatments including ER Formula and Quik Gel directly into the crop. They are also useful when hand-rearing birds. Crop needling is a special technique and requires individual tuition, however, once mastered is an invaluable skill for any bird fancier. Our crop needles have been custom made so that emergency treatments may be administered safely and efficiently without the risk of the needle blocking. Crop needles are available in a range of sizes for all types of birds.
