I refuse to take babies from any of our broody birds, our momma hen only hatched out ONE, and she and the baby are SO overly bonded to one another, she freaks out. she did the hard work for 21(plus 4 more!) days, she went on minimal food,water, and exercise, I just watched. so to me she deserves to do her job.same with your bird
it can take DAYS, or weeks for a momma to get over her babies, as it can with any mother animals, cats will call and call for their babies forweeks!.
thats my opinion, rgular handling, depending on the size of the clutch even with the momma the babies will be somewhat tame, and as they get older they will, just like their mother, will learn to like you.
