I am new to raising chickens and ducks. I noticed what looked like blood in the poop. I thought it might be Coccidiosis but none of my chickens look ill. My youngest son said he feed them some red berries. Should I treat them just in case or wait for signs? Also we just butchered our first rooster, should I not eat it? My hens like to perch on this old dog house and this is what I found.
