Bleeding wings

[Coolbreeze89]

I have a batch of 20 Muscovy ducklings about 8 weeks old. They are in a secure combined coop (8x12) and run (10x30) with 24hr access to both. They’re growing well and feathered out completely...except the wings. They seem to be pecking each other’s wing feathers. I culled a couple that were clearly drakes and being aggressive, but it persists. They were on flock raiser for the first month, and now on 16 % chick crumble. There are two large bowl feeders. They get oats, peas, and nutritional yeast.

Is this a “too many” drake thing (though almost everyone has some evidence of pecking)? I don’t think it’s overcrowding given their total square footage. I used to take the feed up at night but I tried leaving it overnight - still evidence of pecking.

Kind of at a loss. Any suggestions would be appreciated.

Usually featherpicking means they need more protein

Pictures of your setup may be helpful. Do you know your exact ratio?

Personally, most of my birds are on 18% at that age. 16% might be fine, but if you're adding oats, that may be diluting the protein down further. Flock raiser has a higher protein content and is formulated for ducks, unlike the chicken feed you're using. You may try switching over to that and see if there is an improvement.
