Birdie is continuing to progress in her strength, however I now have a new concern which is her constantly opening her mouth - could it be her crop is impacted? She has not been drinking a lot of water and her crop is hard in the morning and she HATES me to touch it. Could the attack from the raccoon cause an injury to her crop OR is the lack of water the culprit?
It could be lack of water. They drink quite a bit normally, I know mine do.
Do you keep her in the dark at night like her normal sleep pattern or do she have a light where she may be eating overnight. If she can see at night, I recommend you make it dark or take out the food before bed, check her crop and then see if it goes down in the morning.
It's possible she has some swelling/injury there as well, but she needs more water, IMO hydration is very important to recovery and will also be beneficial if she has a slow moving or impacted crop developing.
Encourage her to eat WET foods, if she will eat the scrambled eggs add water and offer some grit as well. Sometimes a few (2-3) very small pieces of bread soaked with olive oil will get things moving, she if she wants grit too. Plenty of water. You may have to try see if you can get more water into her with an eye dropper, needle less syringe, or even tube feed her. It's slow going with dropper/syringe. This is what works for me, I do have a work table I use (easier than bending over a chicken), let her stand or sit as she pleases, keep her close, but not squeezing her in, put the dropper/syringe on the side of the beak and drop water, most of the time they will take it. Patience and letting her tell you when she is ready for more helps. You can also gently pull her wattles just a tad, usually they will slightly open up, give just a drop or two of water, let go, let them swallow, repeat. You don't want to squirt a bunch in because they can choke. If you are unsure, go out and watch and study how your other hens actually drink water, this helps you see when she is ready to take another swallow.
