Where'd They Get That Big Chicken From?

The chlorine-washed chicken row carries on and now after one Minister said he was okay with it, another one has piped up and said he would not allow the chicken's washed in a chemical that was used as a devastating weapon in the World War to be allowed in Britain as part of a future deal with the USA.
'No. I have made it perfectly clear, and indeed this is something on which all members of the Government are agreed, that we are not going to dilute our high animal welfare standards, or our high environmental standards, in pursuit of any trade deal' said Michael Gove who is currently the Environment Secretary.
Good for him, especially as Michael Gove is widely regarded as someone who wouldn't think twice about selling his own parents if he gained from it. 
The practise of washing chickens with chlorine is widespread in the US but has is banned in the EU which only allows washing with cold air or water although Liam Fox explained that Americans had been eating it for years with no ill-effects but then they voted George W Bush and Donald Trump into power so that is debatable.
Already the protests have started and i am more than impressed that protesters, with only a few days notice, have managed to wrestle up a massive blow up chicken to carry to Downing Street.
Is there a large supply of different blow up animals holed up in someones garage or did someone have it laying around just in-case such a purpose arose because i can't see how they could have got one made in such a short time span.
Resourceful bunch these protesters.
