i use pumpkin seeds to worm mine, its all natural and with so many people carving pumpkins its easy to get seeds. i also feed them pumpkins that people decorate with, after Halloween so many people throw them away so i offer to get rid of them and it makes people very happy. pumpkins are a major source of feed for my girls at this time of year. also stores will clearance them for super cheap on or soon after halloween. my understanding with the apple cider vinegar is it has to be the natural kind because others they take the good stuff out of it. also with the vinegar you cant use a metal waterer with it.Can we talk wormers? I have had the chicks since March, well then I added a few more over time. LOL They are for the most part 6-7 months old now. I've never wormed them. Should I? Why or why not? I know I will get different opinions. I want to keep my ladies healthy.
