The time I took a hen to the vet for egg binding the vet said that dehydration was the leading cause. For that 4kg hen I was told to give 200 ml of subcutaneous fluids twice a day. Since subcutaneous fluids are hard to get without a prescription, and expensive, I will tube fluids. My preference for oral fluids is something like Gatorade or Pedialyte.Ah, ok! I did not know I should do that, this whole egg bound treatment thing is a new experience for me. Not rude at all, I am very thankful for your advice!I will do my best!

I also give Meloxicam.
I will do my best!

Should I give another dose of calcium? Unfortunately, I just can't get all those fluids into her since I have no tubes or SQ needles. Been trying to syringe as much as I can slowly into her mouth, but she is uncooperative to say the least. She's still up and going out foraging with us, eating some bugs, slugs, and snails (not as many as usual but still something) but will not touch her pellets or wheat.
