I just happened upon this site as I was looking for info on air bubbles in the copo of a baby bird...... I was sad that Marshs posts ended ...... she spoke of an issue with Erwin... I pray he is ok

I myself am raising 4 baby house sparrows.... successfully raised 3 from the last clutch..... they have made nests in recessed lighting out on the porch of my friends house..... the babies keep falling out.... on the first day this happened we found 7

we were so so sad! that we went and got hanging baskets to catch anymore that fell..... we were not aware that they mate more than once a year.... our first batch we saved 3 of the 4 that fell after the original 7 plummeted to their death

The smallest one died, were not sure why

we feed them bird formula.... we were feeding dry kitten food soaked in water..... but from what I had read the formula was the best.... I may try some sardines though after reading this..... I have one who is very much smaller than the others.... today I noticed a small air bubble in his crop..... thats why I was on here lookin for answers..... is this normal? its noting like the pics Ive seen in here, so Im guessing its probably ok and will go away...... anyone ever see an air bubble in the crop? theres mostly food in there but I never saw a bubble in any of the others any advice would be appreciated.... also , what kind of anti biotics are suggested for these birdies?
