Can Use Anyone's Help, Please!

I have a 27 month old Lavander Orpington. She was fine all day but then tonight she became sick with something and I am worried she will not survive. She is not eating or drinking, tail feathers are turned under and her comb is pale. She was eating earlier today so not sure why she has no interest in anything now, not even grass or mealworms which is always her favorite. It has been VERY hot and going to get hotter yet, so I thought initially it was from the heat. I then noticed she looks like she is walking with a bit of a waddle as if she may be egg bound. She has laid 2 eggs in the past 6 days. A bit less than normal for her. I soaked her in some warm epsom salt water for 15 minutes but not sure if it helped her any. I have tried to give her electrolyte water but she does not want to drink. Her crop is quite empty and her eyes and nose are clear without any discharge coming from them. If anyone has any idea as to what may be happening with her, I would truly appreciate the help. I just want to do something for her before it is too late. Thank You

She may be having trouble laying an egg, I would try giving Extra Calcium to see if that helps. Give her 1 tablet asap, then once daily for a few days.
You can find Calcium Citrate with D3 in the vitamin aisle of stores like Walmart, CVS, etc. Give 1 tablet daily, just pull down on her wattles, pop the tablet into the beak and let her swallow.

Take care about soaking in warm water if it's really hot and she's lethargic. It would be better to omit the soaking and just work on hydration.
Offer electrolytes and cool fresh water.
