Combining flocks and rooster question

First off,a mean rooster is SERIOUSLY dangerous,I suggest culling him.Also,it is much easier to introduce younger roo's anyways. He could possibly kill them,RIR's tend not to like other roosters.If you do plan on keeping only two,keep one that is protective and non-aggressive towards you or anyone else.

Have they ever seen each other before?

Also,are the young chickens sick?Or are the big ones?If not,then there is no way they could get ill.

 

I'd get rid of the old rooster and combine them all.

 

Slowly intagrating the 2 flocks should work fine as long as you reduce the number of roosters.If it was me I'd cull the old aggressive rooster and let the 2 young guys grow into the job, they already are living together and have the pecking order pretty well settled. As far as sickness unless you can separate the 2 flock by a pretty good distance if one flock gets sick the other one probably will too. The size flock your talking about doesn't really run a higher risk than keeping them separate.

 

I am sure you do not change shoes or clothes while tending to your daily chores..What one flock has the other ones have it too...
Unless kept in a bio-secured facility which they are not...One large flock might work? Just be prepared for all the usual pecking order fights to take place...
As far as Roosters go....That is up to you too decide...Personally I do not have one anymore...

Cheers!

 

Me too.

Disease really isn't an issue. If one flock on a property has something, they're all gonna have it.

Get rid of mean rooster. They can be protective but not human aggressive.

With that many birds, of those ages, I'd simply put them all together and let them figure things out. You've got enough birds of each group that no one should get singled out and harassed. There will probably be a bit of drama overall, squawking and carrying on, and some deciding who gets to eat first, things like that. But that's all normal when you introduce new animals. Let them play things out, just keep an eye on them. Make sure no one is getting pinned in a corner, or relentlessly pecked. If you have plenty of space, and some hiding places, it should be fine.

 

Bio 'quarantine' time is long over, probably never happened.

I too might advise to get rid of the older aggressive cockbird.....depending on how he is aggressive, more details on that would help.
Is he human aggressive?
Then wait a time to decide between the younger 2, you might be able to keep them both depending on how their demeanor's emerge.

Is the larger facility large enough for 20 birds?
Do you free range? I'm assuming you do as you speak of 'protection' provided by the cock/erels. That can help with integration.
They might not all go into the one coop unless you confine them all there for a time.

 

The older rooster is going to love the idea of more hens. He is not going to like the idea of new roosters. He will fight to prove his worth. There really is no way to introduce roosters to the point of getting used to each other, they need to have it out. Roosters have been known to fight bloody through a fence. So if you mix them, be ready to be able to separate them if it gets real ugly. If you separate them, thinking later you will try again, they will fight again. If the fight is wicked, that relationship is not going to work, one of those birds will have to be culled.

Now a couple of things might happen. The older rooster could whip the younger roosters, and the younger boys accept that lower position. Or one or both of the younger roosters could fight until death or severely damaged to one of the birds in the fight. They may get along for a while, and then try it on again. They are animals, and there is no way to really predict what will happen.

If you cull the older rooster, and keep the younger birds, you will not have a fight now. However, one of these roosters will be the alpha, and one the beta. That might be long term, or it might also one day need to be redetermined. Again, it might just be a skirmish, might be worse.

If you have multiple roosters, this is a risk. Have a set up to immediately separate birds away from each other if a severe life threatening fight happens. Those birds are never going to get along from that point on.
