I may not be of much help but...there used to be (and may still be) an exotic bird breeder on the south side of Austin that also rescued birds. I don't know if they did domestic fowl or just exotics and can not recall their name. They had a sort of exotic bird "zoo" that you could tour and were located just up a little hill road off of Ben White Blvd.
Also, you might try SARA. they are an animal rescue group located just outside Sequine and I am pretty sure they would take them. However, they probably don't have the means to come get them. But you might give them a call ((830) 401-0280 ) they may have volunteers in your area that could assist in their capture and move them to SARA. SARA's website is http://sarasanctuary.org/
There is also a bird rescue somewhere around San Marcos, again I don't recall their name or if they only deal with wild birds but you should be able to get some information about them by calling the Animal Shelter in Austin.
Sorry I could not be of more help. If I could I would come get them myself but that would be nearly impossible to do and may actually violate some law if they are now in a public park.
