Roundworm help

[Cwilkins711]

Hello all

I found a deceased round worm in my chicken run today when I was doing my morning routine. I’m 98% positive it’s a round worm (I’m a vet tech).
It’s hard to say what chicken it came from since they’re all together. What’s the best way to just deworm everyone? They are all varying sizes with the smallest being probably 2lbs and the largest probably about 5lbs. All mixed ages also from 4months to 6 years. Aquasol?

Aquasol (a lower dosage of fenbendazole that is put in water for 2 days, and does not require an egg withdrawal time,) only treats roundworms. The dosage is a little hard to figure out. I prefer 10% fenbendazole given orally for 5 straight days, or albendazole (generic Valbazen which is not available anymore,) given once and again 10-14 days later, and get round, cecal, gape, and capillary worms. Egg withdrawal time is 14 days. If you can get a fecal float, that would tell you if roundworms are the only problem.

If you deworm all your chickens you are creating more resistant parasites than if you only deworm the one with an issue. Some (we’ll call it Y) number of parasites will always survive a dewormer so if you treat X number of chickens you have X*Y number of resistant parasites afterwards. All of the poops now have resistant parasites. If you only deworm one chicken you only have Y/X number of poops with resistant parasites.

My flock sheds round worms from time to time. I feel their keel bones and if one chicken feels especially thin I might deworm that one. Otherwise I let it be. A healthy animal can handle a small parasite load.
