My chicks (2 yr.old) DEFINATELY have round worms. YUCK ! ? ? Are there two types ? Wazine says for LARGE round worms. One of my hens passed a long skinney round worm. # 2. HOW MUCH WAZINE FOR A GALLON OF WATER PLEASE. The whites on the eggs have been thin and runny. Gonna bet this had something to do with it. Dumb me I can't believe I haven't wormed "in for ever". I know better !
