I've had chickens for about a year and a half now. We currently have 36 (full size, no bantums). I've never noticed worms until today. I saw one worm in a solid poop on the roost and a few long ones in a runny small poop outside on the porsch. They look exactly like Ascaridia galli. I've looked up several threads regarding de-worming. I've never had mine on a regular de-worming schedule before (actually, I've never de-wormed). Some have said that it's not needed until you see the worms and then the chickens should ONLY be treated once.
From the hand-full of websites/threads I've read I should either do a dose of Valbazen with a follow up second dose 10 days later (eat no eggs for 24 days) OR do a dose of Wazine with a follow up dose of Safeguard paste 10 days later (eat no eggs for 14 days).
I'm a bit confused on what to do.
Also, we're planning on culling about 15 birds this Saturday. Should I treat for worms and wait to cull? Or can we just eat (possibly) wormy birds?
P.S. All the birds are of varying age. From 3 months to 1.5 years. My egg production had fallen considerably. Could it be due to worms? Some of the older birds are molting too.....
