I'm posting this because I lost a little hen to enteritis caused by capillaria worms and the damage allowed a cocci infection in. I worm regularly, but I've learned that capillaria need more than just the single usual worming because they are tougher. They are supposedly carried by round worms and she had 1 roundworm in her intestine as well. It really shocked me because she's been in a pen for 4 years (silkie) so where did the worm come from? It must have been painful, she was disoriented on the end. I tend to think that this could have been avoided by doing a worming method specifically for capillaria and anything else, or a proper worming with 2 doses 10 days apart . I guess 1 worming of safeguard every few months didn't cut it. My free range flock is worm free . I wonder if there's anything that can also be done to the ground in the pens?
