Hello ! would appreciate any advice on this: today in the morning I was hanfeeding my baby tiels. (they are partially handfeed once a day) but when I grab one baby,he began to scream like if he was in terrible pain and stress (I was only gently holding him) he was attempting to bite my fingers (hadfeed babies dont really bite but he was doing the motion.) I put him back in a box but he wasnt calming down and the I noticed that he can no longer stand on two foot,he was leaning on the side like paralyzed . Two days had passed and he is still on his side in the nest. Parents feed him,but his siblings are fledging, and he certainly wont be able too. Is there any medicine I should try? I cant even understand what had caused this . I wasnt in any way harming him,wasnt doing anything strange, I was handfeeding babies for years.. Please dont advice me to check with vet, the one I have here is dog&cat one and I just have the feeling that I know more about cockatiels,then he does..My questions are-are there any medicines that can return him control? (he can move both foot but cant stand on them) and why did this happen ?? Thank you all for your support !
