Rehoming chickens

Hi all. I recently moved home and in no uncertain terms we've been told we cannot have the chickens in the back garden.

They're pretty old now, and I really hoped they'd be able to just see out their time in conmfort here but it seems like that is not an option.

Can anyone help me with rehoming or donating or whatever? Legit dunno where to go. I've tried two charities that both say they only take "factory rescued" chickens and gave me the same advice as Google does which is real vague.
