[Miss Lydia]

Pic would help. Where?

 

[Brooke17]

My camera has bad quality its mostly on thier wings its red and couple spots on thier body

 

[Miss Lydia]

Losing down probably do you still have them under heat lamp? Notice any nibbling on each other.

 

[Miss Lydia]

Yellow ducklings when they begin to lose down can have redness on their skin. Just wanted to make sure heat lamp isn’t too low.

 

[Brooke17]

They have a heat lamp on half of thier pen and the other half of the ac is closer to my ac i have running. They can be under the heat lamp or the cooler side they have plenty of room to move around if they want heat or cooler. They dont really pick at eacch other. Maybe its just the yellow fuzz falling out. They get enough food and water so hoping its just a body change

We had a lot of Pekin ducklings hatch this year...19 I think. Anyway, I remember noticing a bit of red on them when their downy feathers started coming out. Some also had very noticeable "goosebump" looking skin when they were wet too. Not sure why some got more goosebumpy than others but they all got toweled off after shower time anyway so I didn't fret too much.
As for treats, I haven't found much that they don't like. They're rather spoiled. Besides treats others have mentioned, they love bok choy, tuna and salmon, cooked wild and brown rice, bananas, and blueberries (if you're up for some fun colored duck poo). They also like plain Cheerios softened in water.

Those are some spoiled duckies you have there
