"I've already had a couple of replies.
"One woman said 'I'd love a couple of girls'."
Mr Harrison said, "As far as we're concerned, the chickens are there for the taking, they've got to go, if you can catch them.
"You'll probably need a big butterfly net or something to catch them.
"There are so many of them, maybe 120 or 130 all running around, big ones and little ones.
"Anyone who wants one should come to see me first and then I can direct that person to where they are."
Mr Harrison said, "The roosters are beautifully coloured.
"They [the chickens] are so healthy and just have the range of everything.
"They are really happy birds but they all have to go."
