My hens stopped laying when the weather got cold back around November. About two weeks ago, i put a light in the hen house hoping to stimulate egg production. (So far no eggs.) Today when i went in the hen house to check on them, i noticed quite a bit of blood on the roost underneath the light bulb. The light is high enough for them to roost without touching it so i don't believe one of them was burned. And besides, it's a CFL which should not get that hot. I have one rooster (a sweet Buff Orpington) and six hens. They all look healthy with no obvious signs of an injury. There was so much blood you can see where it covered about a 6 inch section of the roost and actually dripped off. Since they all seem to be fine, i'm not sure what i (if anything) i should do. Any suggestions? Thanks!
