The older chicken will not no eat or drink and when we shove food down her throat she spits it back up. The other chicken is now limping. What should I do? Please help me!!!
I'm sorry you're still having trouble.
Do you still have them both separated from the flock?
It sounds like the older chicken may not be able to process her food. Is the crop emptying at all if you do get food into her - is she pooping? Some hens can hang in there for a while, but she may be declining due to her injuries and age. If she continues to not eat or be able to process her food, then you may need to consider putting her down.
The other chicken, if you let her back into the flock, then she may have re-injured something. If you haven't done so, then you may want to separate her so she can heal a bit longer. Add some poultry vitamins containing B2(Riboflavin) to her water to see if she improves over the course of a few days.
I know you are doing everything you can and taking good care of both of them.
