ok, she NEEDS to go to the vet, can you take a taxi? call someone for a ride?
egg binding is extremly serious, it causes internal bleeding and organ rupture, let alone being extremly painful.
I will be very honest with you, most birds, specially tiny budgies, who do not get medical care immediatly, do not survive egg binding.
is the egg out all the way? or part way?
If you can towel her and pick her up gently, without squeezing her abdomen, then rub some olive oil "gently" onto her vent.
this will help lubricate and ease the egg out.
if you have a heating pad, stick it into a pillow case and stick it into her cage, take out ALL perches, this will make her have to go to the floor.
set the heating pad on medium, and use any kind of thermometer (even one you use to take your temp with) and check the temp every half hour, it NEEDS to be 90-95 degrees in her cage, cover her entire cage with a blanket except the front, this will keep heat in and calm her.
give her orange juice to drink, put it in her water container and mix in a little water, this will give her a boost of energy.
take a regualr egg from the fridge and crack it, throw the inside away and wash out the shell, microwave the shell for 1 minute (to kill any germs and cook the goop that lines the shell) make sure the shell is cool to the touch and give it to her... this is immediate calcium.
she is egg bound because she lacks the calcium needed to push it out and create a hard egg, she needs calcium.
these are things you can do at home, do them IMMEDIATLY, specially the heat and the egg shell.
to towel her, throw a towel over her and pick her up in it. this is the easiest and gentlest way to get a nontame or hyper keet.
just dont squeeze her abdomen and she will be fine.
keep calling the vet if youcan, and make an appointment for tomorrow morning to get her checked out.
keep us posted, i hope she comes through. and remember to be calm, if you are calm she will be too.
