2 Chickens dead, 3 with bloody vents

[BFowl]

The title really says it all... any suggestions?

 

[Col1948]

Have you got any male ducks by any chance?

 

[BFowl]

No I don't

Did something attack them? You will get more help if you include as much information as possible.

Are they injured/wounded, or are they pooping blood? More info needed, better picture of the vent(s).
