What kind of evidence should I be looking for to determine if by birds have worms?
I've heard that people generally treat their birds for worms regularly anyway so I need to determine how and when should I treat my flock.
Should I treat the 13 week olds at the same time I treat the rest. 4 of my 8 birds are laying after treating what is the waiting period before being able to eat the eggs?
Would be best to get a bunch of poop samples and have a fecal tests done, but if that's too much work, just buy some Valbazen and give 20mg per 2.2 pounds and repeat in ten days. That dose will effectively treat most worms. Treat all birds.
To calculate the proper dose, take the weight of bird in pounds, divide by 2.2, times 20mg, divide by 113.6 (number of mg per one ml of Valbazen). The answer will be the amount for that bird.
Examples:
1 pound pullet
1/2.2 x 20/113.6 = 0.08ml
5 pound hen
5/2.2 x 20/113.6 = 0.4ml
10 pound hen
10/2.2 x 20/113.6 = 0.8ml
