Sounds like she is in distress. The purple comb indicate blood flow problem or illness. She is not that old, the oldest living hen was 15-16 years old!
If she is in and out of the nest box, it is most likely a reproductive problem. It sounds like she has been ill for a while. If you can get her to eat and drink water she may have a chance. If her abdomen is swollen you must take great care to support that area when handling her.
You should also be able to use your "blackmore's executive B stress formula", just crush and administer 1/4 teaspoon twice daily. Till you can get poultry vitamins, she really needs vitamin supplement now.
I try to use herbal medicine when ever possible. Here is my recipe for Herbal Antibiotic and Immune System Support. The herbs can be purchased at Wal Mart or any pharmacy.
1 (760 mg) Capsule, Echinacea
1 (400 mg) Capsule, Golden Seal
1 teaspoon Hempseed Protein Powder (or other protein powder)
2 teaspoons warm water
1 teaspoon Agave Nectar, * optional
Dosage for chicken:
weight 5 lbs. = 1.25 mL, twice daily
May be given three times daily, 7 days, for severe symptoms: lack of appetite, diarrhea & lethargy.
Use for no more than 10 days.
Suggested Treatment Plan:
First move the hen to a hospital crate where you can care for her.
- Each day - 5 minute bath in warm Epsom salt, 1-2 cups in a dish tub of warm water.
- Twice daily - Syringe feed Herbal Antibiotic and Immune System Support
- Daily vitamin supplement till eating vigorously
- Provide meat protien, diced fruit: grapes, melon or pears, Cooked grains
- Rest, no roosters, pestering hens or kids!
Hope this helps...don't be discouraged. Just do what you can, keep us posted.
God Bless and peace to you.
