I have a couple questions about broody hens. I have one broody right now who is sitting on a mallard egg and 10 chicken eggs. I made sure to set my duck eggs first and then I added the chicken eggs later so that they will all have the same hatch date. 1) Once the chicks hatch could I put a couple more ducklings under her? Provided the chick makes it to hatching it will be the only duckling. I intend on getting more ducklings regardless. My thought process is that it wouldn't be good to have one lone duckling. 2) I noticed another hen must have laid in the box. Will a broody still sit eggs that have staggered hatch dates? (I know this is by no means ideal.) 3) Will a broody hatch multiple clutches a year?
