My hen's underside is firm, and she smells bad. Help!

First check her for being egg bound,put on gloves w lubricant and do a cloacal exam,see if you can feel and egg. Soak her in a warm water bath. If you feel an egg you can also(besides warm water soak)give her a calcium or tums tablet or liquid calcium. Keep her quiet and in a dark area.

She could also have a condition called peritonitis,but check for egg binding first.

For possible sprain leg,can you feel any swelling? Soak her in an epsom salt bath this is great for sprains/sore muscles and for cleaning.

Green poop is from not eating enough food. You may want to consider tube feeding her.

 

Lymphoid Leukosis Synonyms:
visceral leukosis, leukosis, big liver, LL Species affected: Although primarily a disease of chickens, lymphoid leukosis can infect turkeys, guinea fowl, pheasants, and doves, but not on a large scale.

Clinical signs:
The virus involved has a long incubation period (4 months or longer). As a result, clinical signs are not noticeable until the birds are 16 weeks or older. Affected birds become progressively weaker and emaciated. There is regression of the comb. The abdomen becomes enlarged. Greenish diarrhea develops in terminal stages (see Table 2).

Transmission:
The virus is transmitted through the egg to offspring. Within a flock, it is spread by bird- to-bird contact and by contact with contaminated environments. The virus is not spread by air. Infected chicken are carriers for life.

Treatment: none

Prevention:
The virus is present in the yolk and egg white of eggs from infected hens. Most national and international layer breeders have eradicated lymphoid leukosis from their flocks. Most commercial chicks are lymphoid-leukosis negative because they are hatched from LL-free breeders. The disease is still common in broiler breeder flocks.
