thanks.
eeee those links don't work. i did manage to get some greek yoghurt and acv soaked pellets down her.
That's odd, I just tried them, and they worked for me.
Basically it is soaking the hen in warm water and gently massaging her tummy to check for a trapped egg and helping it out if it is.
For the prolapse, using hemorroid or hydrocortisone cream and gently pushing it back in place. Some like to use honey.
For infection, administering antibiotics.
Hopefully they'll work for you here:
