I really wouldn't use honey this time of year, it'll be a magnet for bees and wasps. Just pop into the shops and get a haemorrhoid cream for humans like Prep-H, just don't tell the pharmacist it's for an animal or they're not allowed to sell it to you.
Then proceed as per Bionic's instructions, it's essential to be very slow when reinserting it.
I've had a few birds that prolapsed over the years, they were fine afterwards and laid again. Only 1 had to be put to sleep after the second time (and only her 3rd egg) as too much of her insides had come out, happened whilst we were in holiday and the tissue had become necrotic, she had only just started laying.
