Can I house 2 month old pullets with year old Hens?

[BiancaMiller]

Hi! I recently purchased 2 pullets that are 2 months old; ameracuana and a Rhode Island blue mixed with cuckoo maran. I also purchased 8 other hens which are a year old and are golden comets. I am currently not keeping the pullets outside due to the fact that I am scared the older hens might injure them. I’ve also got a turkey hen and a duck (unaware of gender). Would it be safe for me to house them with the rest of the flock, or should I wait until they get older?

I would wait till they are older, especially because of how many more older hens there are. A rule of thumb I use is right around the time that they lose their chick voice is a good enough time.

Thank you, I probably will do that!

Not sure about the duck and especially the turkey.
Turkey can be very aggressive.

I integrate chicks young, I find it much easier once you get it set up.

For now......
Integration Basics:
It's all about territory and resources(space/food/water).
Existing birds will almost always attack new ones to defend their resources.
Understanding chicken behaviors is essential to integrating new birds into your flock.

Confine new birds within sight but physically segregated from older/existing birds for several weeks, so they can see and get used to each other but not physically interact.

In adjacent runs, spread scratch grains along the dividing mesh, best if mesh is just big enough for birds to stick their head thru, so they get used to eating together.

The more space, the better. Birds will peck to establish dominance, the pecked bird needs space to get away. As long as there's no copious blood drawn and/or new bird is not trapped/pinned down and beaten unmercilessly, let them work it out. Every time you interfere or remove new birds, they'll have to start the pecking order thing all over again.

Multiple feed/water stations. Dominance issues are most often carried out over sustenance, more stations lessens the frequency of that issue.

Places for the new birds to hide 'out of line of sight'(but not a dead end trap) and/or up and away from any bully birds. Roosts, pallets or boards leaned up against walls or up on concrete blocks, old chairs tables, branches, logs, stumps out in the run can really help. Lots of diversion and places to 'hide' instead of bare wide open run.
Good ideas for hiding places:
