Hi all. I let my girls out of the coop this morning and one of them squatted for a rather large poo right away. I noticed it looked kinda bubbly and so took a closer look to ensure all was well. As I did so, I noticed that they weren't bubbles at all but squirming little worms. I have no idea what kind they are because they don't look like the round worms I have seen before. They are small and thin and the round worms I have seen are rather large. The only wormer my feed store sells is Wazine which I bought but am hesitant to use because there is an egg withdraw period. Then from what I've read, I would have to retreat with a more effective wormer like ivermectin which would require another withdraw period. Is there a one shot wormer that I can use that covers all worms and is still safe for my hens. I'm all for treating with cayenne and DE in between worming treatments but please don't suggest them for now. I obviously have an infestation.
