Just noticed today some worms in my hen's poop. Dont know what made me look but I did. She is perfectly healthy, better feathering than the rest of my flock and has never had a problem with anything, until now. I thought if a chicken had worms, their health would deteriorate but not in her case. Luckily I saw them. I am wondering how long these worms will last that she pooped out. Is the coop infested now? Do I need to treat with something before I allow them back in there? I treated with Eprinex today to take care of these things. They are very gross!
