lacking but present in ducks, geese and others, fertilization is internal, amniotic eggs with much yolk and hard
calcerous shells, incubation is external, young can be active on hatching, or helpless and naked (altricial).

The Making Of Transgenic Birds
3.1 The General Process For Genetic Modification Of Farm Animals
STEP 1: Isolate the DNA desired molecule
STEP 2: Extract fertilized egg from the bird
STEP 3: Inject the extracted DNA molecule into the nucleus of the fertilized egg with a micro injector
STEP 4: The DNA integrates with the nucleus of the cell.
STEP 5: The eggs are transferred to a foster mother.
STEP 6: In due time, after the gestation period, the young/eggs are laid.
STEP 7: After hatching, a blood sample is taken from the bird and tested for presence of inserted DNA.
