Hello.
I don't think 
my experiences would be of help, 
but still... if ever the mistakes I did can be avoided... :
	
		
	
	
		
		
			Do you have a drake jail ?
		
		
	 
Yes.
I 
do have a drake jail, but... to be 
specific, what I call my 
"drake jail" is, in fact : 
a coop connected to a run + half of my current vegetable garden.
	
		
	
	
		
		
			What is your experience ?
		
		
	 
Pretty 
mixed, actually...?
I am happy enough with this "drake jail" : indeed, I can let the drakes roam freely in a big enough space, and so, run as much they like...
...But : the drakes can still see the girls; and so, letting them roam in (half) the vegetable garden means taking the risk of them 
flying away to go to their girls...
(And two of them actually already 
did...!)
Besides : if I keep the drakes together when hormones are out of control
 (because of mating season), then some of them might fight with each others until I separate them OR put girls with them...
Nevertheless : if done 
right, then the "drake jail" is a good solution to protect the girls from overmating...!
	
		
	
	
		
		
			Why did you decide to build a drake jail ?
		
		
	 
I did 
not build a "drake jail", specifically : 
I am just using what I already have, which is a space where I can separate the ducks if needed - for 
whatever reasons 
(like : bringing home and carefully introducing new ducks to the older ones - for example)...
	
		
	
	
		
		
			Are all your drakes together ?
		
		
	 
Apart from mating season, my drakes are always together.
Some are so bonded I can not even separate them, because they prefer to be with each other than to mate - even during mating season.
	
		
	
	
		
		
			Do you rotate your drakes to be with the ladies ?
		
		
	 
Until now, yes - given I wanted to avoid 
any risk of inbreeding...
Otherwise :
 only when hormones are so out of control I can 
not put the boys together without some of them ending up fighting.
	
		
	
	
		
		
			Do you keep one of the drakes with the ladies always ?
		
		
	 
No.
Because I want the girls to be able to 
breath without worrying about the boys hurting them...
(My ratio male-females is pretty bad.)
So : I let the boys fertilize the first eggs of the season until my first (chicken) hens are broody... 
then I put the drakes in drake jail.
And I manage from there - meaning if a drake is much too agressive with the other boys, I put him with the girls again for some days or weeks.
	
		
	
	
		
		
			Who has or doesn't have access to your pond (if you have one) and when ?
		
		
	 
I don't have a pond.
Instead : my ducks have an unlimited access to a 400 liters pool - among other things...
But when I put the drakes in drake jail, they don't have access to this pool anymore...!
So : I put 
mortar troughs and 
dish basins -
 filled with water and cleaned everyday - in their part of the vegetable garden.
	
		
	
	
		
		
			What are the biggest mistakes one can make when setting up a drake jail ?
		
		
	 
If the drakes are still roaming free in a part of the yard, then :
• letting them see and/or hear the girls;
• not using a high enough mean of separation (enclosure).
	
		
	
	
		
		
			Does the set up influence the ducks behaviour ? How ?
		
		
	 
Yes.
If the drakes see and/or hear the girls, and if the enclosure is not high enough, then some of them will eventually
 try to fly over it in order to go mate with the hens... 
and they probably will even succeed.
(I own two Indian Runner drakes that have learned to fly, and when kept separated from the girls during mating season, they fly away from their "jail" in order to go to them... 
once a day...!)
	
		
	
	
		
		
			Really anything drake jail related you do or don't do, what you learned works or doesn't work, what to look out for what to avoid... Please share your stories and knowledge with me and other newbies.
		
		
	 
I clearly need a 
better drake jail...?
(In fact, I need 
several drake jails...)
But first : I need to get more hens for my drakes, or at least get rid of some boys...
Maybe then a drake jail would not even be necessary
 anymore?
	
		
	
	
		
		
			Any and all information on the topic is welcome and appreciated.
		
		
	 
Drakes that are separated from their girls during mating season are soooo ready to learn to fly to go mate with them...
(One of mines literally did 
specifically to be able to 
mate, and I then had to go catch him 
almost everyday to keep him away from the girls...!!)
