My 4 month old black swedish duck does this weird thing every morning. I get her out of bed right in the morning and she does this thing where she is standing but kind of flattens out and she puts her head forward. I try to move her by pushing her gently on the back (she usually doesnt like to be touched) but in this time she doesnt move at all. I end up picking her up and moving her to where she is suppose to go and then she seems to be fine. I dont understand whats going on? Any ideas?
