Hi, need a second opinion on gender ratios
Currently I have a flock of 11 hens (no roosters) that share a coop and free range with my 8 ducks including 6 duck hens and 2 drakes
So oldest drake is a year and half and has never went after the chickens and isn’t to aggressive with the duck hens he’s also a buff so pretty small the new drake is just a couple months old and a Muscovy he’s young enough hormones haven’t hit so idk how he’s gonna be with the hens
So trying to decide do i need to rehome one of my drakes or do i need to get more hens to keep gender ratios in check
What do you all think?
From what I've been told by word of mouth and what I've seen supporting the same online is that they really should be separate. As stated above it's horribly painful and can lead to injuries resulting in a cull or death instantly afterwards.
Yet I know ONE person who has a peacock, hens, ducks, and geese and somehow he's kept enough females per flock of species that he assumes that why it's been successful.
Personally it's so easy to build shelters and coops that are fully secure I'd not risk my poultry even if they're just strict layers or for butcher I'd still not risk it as the eggs and meat reaching maturity would be most important to me.

Have you considered adding true sexed hens to the flock and maybe the same to your ducks? Little babes are fun and great for more pet interaction experiences, the imprinting, but it could be useful adding them as an extra female option.
Even being mated too frequently by a drake or rooster can kill a hen or mama duck.
I think your guts speaking to you!
Theirs amazing guides on all types of layouts and designs of secure runs and coops online you can check out. Supplies usually very basic and easily acquired.
I'm currently gathering supplies to build two new ones on my property because we got 5 ducklings and worry we may have a bad situation if it's one female 4 males or even 2 males 3 females, etc, not cozy safe in my own preference for their care. But I'm also a helicopter mom who's building a wheelchair this week for my disabled feather buddy, Sugar. My father in law who was a 4th generation farmer wanted me to cull but I begged to have a chance at making her life happy and accessible so long as she's not in pain and he agreed. Now he loves Sugar and Sugar has improved and my father's impressed it was even worth the time. In days she was showing signs of improvement so he said she stays. Currently waiting for her diaper to arrive since she needs so much human care she needs to behave and wear her panties.

So as above is indicating, I'm extremely attached and can be overly cautious.
Sure hoping things stay civil!
