I have also read but haven't tried is to put the chicken in the dark for four days, giving it only four hours of light per day. This will temp stop the chicken producing eggs while it gains strength.
One avenue i am looking at is for my chicken to have an hysterectomy, i don't have any information about the op or its success rate but it seem to be the only way to stop it occurring again. (If anyone does know of a chicken which has had this op, i would be interested to know how it went.)
Hi bealy bird. Welcome to the forums and thank you for your brilliant post.
I like the idea of putting the hen into darkness, I would stop ovulation I'm sure, and give the hen a chance to recover.
I talked to a"bird vet" about having a hysterectomy for my gorgeous Gerty but she became far to ill and weak to have survived an operation. The vet did however explain a bit about the condition and operation to me which I'll try to explain as best as I can:
Egg peritonitis is caused by an ovum (yolk) being released from the ovary but not entering the fallopian tube and instead staying in the body cavity. The hen's body reacts to this and produces a lot of fluid in the body cavity (ascites). The body eventually seals off this foreign material (the yolk) in an abscess and the hen recovers, until the next time it happens. This peritonitis can easily become infected from bacteria in the gut and unless treated with antibiotics the hen will die.
When the vet performs a hysterectomy not only must the reproductive organs be removed but all of the abscesses which have been previously formed must be found and removed too. This operation is very tricky and as you can imagine requires a vet skilled with birds. The hen has to be in a strong condition (no peritonitis at the time) to stand any chance of survival.
I hope this information is helpful to anyone considering this route for their sick hen.
