So, one of my Brahma girls has had runny poop ever since I brought her home 2 wks ago. She's about a year old and hasn't yet laid me an egg, although her sister has laid four. Her comb is much lighter than her sister's too. Today I noticed her poop had small red "strings" in it. I'm assuming I'm looking at worms, but can't seem to find a good reference to it in my chicken book. Any clarification you can give me? Any suggestion for treatment? Thanks.
