Can new barn cats be accepted in a now small feral colony?

Hi everyone,... I'm looking for help or advice. 6 years ago ( around) I had been feeding a few stray cats in my yard. these cats only wanted the food I had to offer,.. Otherwise they'd run and hide out of fear of people. Long story condensed,... One of them gave birth to a litter of 4 in my garage. No sooner were those kittens up and walking/ about 3 weeks,...another cat in the neighborhood had a litter under my porch! Add 4 more baby's to the mix. Of which,...I ended up bringing that whole litter to a vet because they had eye infections that were obvious to me, we got them all better with antibiotics and eye ointment. fast forward,.. I socialized and even bottle fed most of those 2 litters,..and found all of them great homes. I kept one strictly inside. Well over the years thanks to our local TNR program that I contacted to get all of the cats I knew of in the neighborhood fixed,.... The strays or ferals have diminished. Even the few I cared for over the years have passed on. 2 got hit by cars,..one got very sick and died. My question,... Finally! [emoji]128522[/emoji] I'm down to 2 adult ferals ,...semi socialized to just me and my family. To Anyone else they are feral.... Run and hide,...hiss. My question is this,... I'm aware of a farm of 10 barn cats whose owner is sick and they need to re home the barn cats or bring them to a shelter. Can I easily enough take in a couple of them to live in my garage shelter with my last 2 ferals?

If it will be easily, difficult to say. But there is no lack of food, thus no competing for it.  And now its good with place too.  So you do have a fair chance, especielly if the new bees are neutered / spayed in good time.  Yes, please, try.

Try to make some sort of scent swapping.  Perhaps their barn cats smell, set in under the food plates of your outside residents.

I really hope you do manage.  Sending a bunch of semi-ferale barn cats to a shelter is just a half complicated way to pts them.    It were more merciful to do it there on place, if such is their fate.

I wish you good luck, both with this new addition, and to you personally.

Tx for caring.

I agree with StefanZ. If there is enough food, there shouldn't be territorial issues. And absolutely, take these cats directly to the vets to get spayed/neutered (if not already).
BUT BUT BUT: these barn cats may very well try to return to the barn (Trap Neuter RETURN not remove), regardless of how far away the two locations are. The general rule of thumb is to keep the removed cats in a confined space (like, a room in your house) for at least two weeks.
Good luck; you are a kind person.

What a dear person you are! If you have a shed, you might be able to confine them there. If possible, use large dog crates in the shed. That way, they can't bolt out when you open the door. Confining them is the only way to ensure they learn to recognize their new home.
