baby lovebird liquid droppings
Hello. My lovebird recently laid 6 eggs but because of the lack of humidity where I live, only 2 of them hatched. One of them has died but the other is still alive. The reason for that is that the hen had stopped feeding them but i noticed it too late. I don't know why that happened but I pulled the baby so I could hand feed it myself. The first few days were difficult of course, not because I had to feed the bird every 2 hours, but because it was difficult to find the formula. I don't live in the U.S.A so things like that are almost impossible to find at the pet shops here. But I have found something called "Egg food" which is a mix of seed, egg, a lot of vitamins and honey. It comes in the form of powder with tiny chunks. So I've fed it that for 2 days but a few nights ago his crop started emptying really slow (I've waited 8 hours for it to empty so I could feed the next meal) . I've made a brooder with a light bulb, and I've always fed the food not lower than 40 degrees Celsius, about 1-2cc each time.
The problem I have now is, since I changed to the baby food, because I thought the "egg" food was the problem, his droppings aren't solid and they turned a darker color. I changed the consistency from a little thin to a pudding consistency but it doesn't seem to change anything. There aren't any avian vets in the area (the one I've found on the internet is 7+ hours away) and the vets I've talked to don't know much about it.
Is there any way I can fix this myself? Should I change back to the old food?
Any suggestions are much appreciated.
