My chickens are two and three years old. Two weeks ago I lost a New Hampshire Red that was three weeks old. She had been sitting around for days and then one day was on her side gasping. She really suffered. The Vet cam the next day so I had him look at her. He said she was very thin and had mites. (I lost a New Hampshire Red a few months ago the same way)
We clean the coope and yard and put diatomoatios earth everywhere, sprayed with the lemon oil the vet gave me. I even treated another New Hampshire Red that was thin and looking like she is getting sick with pyrethrum. The vet said he doesn't like to use it, so I treated only the one.
We put worm medicine in the water for round worms and apple cider vinegar in the water for parasites. I also upped there food with a high protein mash.
The vet gave me a prescription for metronidazole. I treated the sick chicken and the only other New Hampshire Red, 5 days 2 times a day .2 mil.
The sick New Hampshire Red chicken is looking much better and is up and walking around. The other New Hampshire Red is now looking very sick. Lying one her side. I don't know if she will make it today.
The very sad news is that this morning an Americana (2 years old) was lying on her side. I brought her out and put her on a towel. She gaped a few times and died. I had seen no signs of sickness.
I have 4 more Americana, The 2 New Hampshire red (1 sick) and 3 Buff cochins bantum hens and one nasty buff cochin bantum rooster.
Does anyone have any ideas of what this might be.
They are not free range now, but they were during the winter (until 3-4 weeks ago). They live at a nursery with gardens, so we keep them in during the months when they could destroy a garden. When free range their first stop was always the bird feeders. One day there were pheasants at the feeder with them.
Please let me know if you have experience with this.
