Great info. Thanks!!Even an 18 is too small for crumbles unless you put them in a blender first. I'm too lazy, so I use "big Bertha", the 30... Takes less than three mintutes to make the mixture, catch the bird and tube 120ml-180ml (2-3 60ml syringes for the bigger birds).
*Start off giving 2-3 ml per 100 grams of body weight and slowly work up to 5 ml per 100 grams of body weight. The average 5 pound hen should get 45-70 ml to start.
