You really need to note that Aquasol SafeGuard (200 mg fenbendazole per ml) mixed in water is only for roundworms when given at a low dose for 5 days. It won’t treat more deadly capilary or gapeworms. When the 10% SafeGuard Liquid Goat Wormer (fenbendazole 100 mg per ml) or the Equine Paste is used orally and undiluted for 5 days, at 0.25 ml per pound) it will treat round, cecal, capillary, gape worms. The 10% is also safe, and much less expensive for the amount per dollar. I think there will be a lot of confusion wi
I want to clarify the differences to avoid any confusion.If you are referring to post 2, wyorp rock said to use the correct dose 0.23 ml per pound for a chicken of SafeGuard liquid goat wormer 10% fenbendazole. That is the dosage most of us here use, and have used for many years. Chickens require a higher dose for capillary worms. Here is a thread about that and read post 2:

I feel like there is going to be a lot of confusion with posts about Aquasol and the usual SafeGuard 10% wormers.
Safe-Guard AquaSol is a 20% solution (200 mg/mL).
Safe-Guard Suspension for Goats is a 10% solution (100 mg/mL).
Both contain the same active ingredient: fenbendazole.
Dosing differences:
- Goats (ruminants):
5 mg/kg body weight, single oral dose
→ 0.023 mL/lb (label: 2.3 mL/100 lbs) - Poultry (monogastric):
1 mg/kg body weight, administered via drinking water over 5 consecutive days
→ 0.00227 mL/lb/day × 5 days = 0.01135 mL total (20% solution)
(half the total volume compared to the goat product, but same total dose - 5mg/ml)
Important: Chickens (monogastrics) and goats (ruminants) metabolize drugs very differently. While fenbendazole is generally safe, the doses described in other posts are wasting product at best — and posing risk at worst.
Formulation matters:
AquaSol is specifically designed for water administration, with a fine particle size that keeps it suspended longer in water. In contrast, the goat suspension is formulated for oral drenching, not for mixing in drinking systems.
Full transparency: I was involved in bringing Safe-Guard AquaSol, the BYC-specific product, to market. I hope this helps clarify dosing for these products. Happy to answer any questions.
