I was cleaning my coop this morning and when changing the pull out drawer where the poop drops through onto newspaper there was a bunch of small, about this long ---- oval worm looking things. I didn't get a picture i just wanted them out but now I'm worried. Could my chickens have worms? I clean the coop every 1 1/2-2 weeks and have 3 fairly young chickens. One is a little of 8 weeks and 2 are about 6 weeks. We did just introduce the younger ones into our coop about a week ago. Please help!
