While retreiving eggs this morning, I noticed two stacks of poop with blood in them. All other poop looks normal and I'm not noticing any foul odor or strange behavior from my hens. I have 15 hens, six of which are only 12 weeks and two which are getting ready to lay (EE's around 22 weeks). My hens have free access to pasture and are usually on either Layena or Flock Raiser or some mixture of the two. I did, however, change their feeds some last week to rid my stores of a few half bags. I mixed a 25% protein super gamebird with a 16% protein turkey finisher, which they just finished. Is this definately worms or Coccis (sp?) or could it be something else? Is bloody poop ever normal? What would you do next? Thanks in advance for your help.
