During April, Northern Bald Ibis eggs hatched on Moroccan colonies.
As ibises don't lay at the same time, chicks could also have very different ages. In fact, besides big chicks there could be also unhatched eggs, as seen in the next picture.
Ibis lay, in general, three eggs that hatch after 24-25 days. During the 40 to 50 days that last the development to fledging, is not unusual that some chicks dye, thus it's normal that just one or two of the chicks fly per nest. In fact, average breeding success last year was 1,3.
