We Just bought an grey about one month ago, she is 13 and came from a family with one other female grey. Last night within about 30 seconds she went from normal to looking and acting like she was in extreem pain and needing to pass something. Then about three minutes later she passed an egg on my BFs shoulder. It smashed on the floor so we threw it away, I called the previous owners and she had never laid one at their house before. This morning she is kind of listless, just sitting fluffed on her sleeping perch, leaning to avoid us and not get on our hand to get out. Is this normal? Is she sore, missing the egg? Im very worried she may be getting sick??? she did eat and drink after she laid the egg but didnt throw her toys around like she does every night.
