Only true ways to know about worms are to see them in the poo or have a float test/fecal test done by your vet. Runny poop is a common sign of a digestive upset due to any number of causes from new feed, spoiled feed, nutritional deficiency (rare when feeding commercial mixes), overheating and drinking too much water (summer problem) or intestinal upset from worms. Spring is notorious for worm problems with the muddy conditions.
If you don't have a regular worming schedule you should plan to use a wormer or have a fecal check done before the birds begin to loose condition.
I have a few 8 year old hens going strong.... so anywhere from 3 years (some production eggers die young from reproductive tumors) to upwards of 10 years for some lucky ones (usually barnyard mutts are the healthiest group in my experience). I love are old girls... they are the best.
What wormer, how much, and how often? I tried doing research last time with wormers but there are so many different kinds and different suggestions. I just need someone to spell it out for me and I'll get it done.
The chickens have regular solid poop, runny poop, and dark black poop. It all seems pretty normal, but the poop on their feathers is not normal for us. I've been checking for worms and have not seen any but could there be some kinds that are too small to see?
ETA: I love our old girls too! They're the friendliest. I'm guessing they're around 5 years now so I'm happy to know they can be around for a few more years!
