I hope baby dove will eat and drink. That is really important. I have rescued a baby mynah and 2 smaller baby birds. The smaller birds didn't make it
. One was already wounded badly. I had to crush bird seeds and mix with water to feed it and I copied that from my budgie who raised her young ones by eating seeds and then regurgitate it with her saliva to feed her babies. Unlike Canada, back in my country we do not have any wildlife agencies to help so I had to either try and do it on my own or see them die. The mynah and crow was easier as they are omnivorous and eats a combo of meat and vege. The mynah actually lived and was freed later on.
