Do you currently have chickens? Or are you just housing the ducks where the chickens have been?
If you are housing both chickens and ducks together no need for different feeds. Grown ducks can do fine on a standard poultry (chicken) feed, but nutritionally all flock food with around 20% protein...
Im not sure if there is anything that will help if her oil gland truly doesn't work. If is a matter of just getting it to function encourage her to get wet and preen frequently.
I believe your bird is a pullet. Those familiar with barred breeding would assume having that much white would make it male. Seeing it as a younger bird this definitely could have lead to those knowledgeable about breeding saying it is a male.
The mixed breeding has affected the coloring. I'm...
If I'm picturing your waterer correctly, the little black cap is to plug the hole where the water comes out while filling the waterer. In order to use the waterer you will need to find another way to fill the hole while filling. Once it is filled screw the lid back on first then remove the...
Has it been like this since you got her? How much does it affect her? Does she lay down frequently? Is she not able to move as fast as the other ducks? Any signs of actual pain?
If the eggs were put under the hen at the same time, they should hatch within a day or so if each other. Candeling a egg that is about to hatch should show obvious movement of the chick in the air cell. A moving air cell would be a sign of a dead egg.
If you want more chicks you could try day...
Hens that have been laying for a year and a half will take a break. Molting will likely begin soon. In the future they will take laying breaks more frequently.
Not all pullets are going to react to your hand like it is a rooster.
You can switch to layer feed now, but you don't have to. Chick feed or All Flock type feeds have higher protein percentages and are usually a bit better nutritionally than layer, They work well for all chickens, but the...
I use black rubber bowls like sold at tractor supply. They are flexible so on really cold days the solid ice can be broken out and new water added. It my not be about heating, but about making sure the chickens can drink a couple times a day.
It depends on if the person who is going to raise them wants to provide heat ect. That young ducks require. Ducks form bonds and it will take the mom a bit to adjust when ducklings are removed, but she will adjust quickly.
Ducks are actually quite hardy when it comes to cold weather. If ducks are not trained to go in at night they will choose to stay outdoors. If your run is truly predator proof no need to force them into a coop.
