I'm the one who posted about my duck Blossom. She had 2 ducklings hatch and was a pretty good attentive Mama. Something snagged one of the ducklings the first week, then we started putting Blossom & her surviving babe in the duck house at night with the drake & 4 other duck hens. Since my son was the one to check on them before latching the door for the night, and this duckling was the sixth member of the little flock, he named her Six.
Six did all right following Blossom and hanging out with the rest of the flock, her dad & her aunties. But one day the drake started bothering Six, biting her on the back of the neck, even carrying her around in his beak. He took a dime-sized chunk of skin out of the back of her neck. So I took Six out of the flock & put her in a pen with some other chicken chicks that were her same age.
Six seemed more upset than Blossom about being separated. Blossom didn't seem to miss her baby very much, not much at the start, seemed to have forgotten her by the next day. Six settled in with the chicks, stayed with them for about a month, and now is a part of another group of 4 teenage ducks a few weeks older than she is.
Maybe Blossom would have done better as a Mama if she'd been kept confined in a pen alone with Six. Though it wasn't really her lack of parenting skills that made me take away Six, but rather the drake's aggression towards little Six.
Right now I have another Khaki, Myrtle, who is setting on eggs. She made a nest for herself and sat for over 4 weeks but none of the eggs hatched. They may have been duds from the start, too old to develop. She's a fierce broody duck, hissing & biting anyone who comes too close. But the eggs may have been too old before she began to sit. She was probably working on the clutch only sporadically, laying sometimes in the duck house, other times in her nest. After 4.5 weeks we swapped her old eggs for some new fresh ones. If they hatch they're due at the end of this month. She's such a intense broody that we thought she deserved a second chance to hatch ducklings.
