I rescued a dying duckling the other day and I also have 4 other ducklings which I incubated and hatched out. They’re about 2.5 weeks old. The rescued duckling I estimate to be about 3 days old and I tried to introduce it to my other ducklings right away but the all came and started attacking it and jabbing its little head I really want them to like each other but I don’t know how to make them friends ¿
