There are so many interesting ways they could have gone with this change. Were they really so pleased with the line "ten for a hen" that they went with a chicken auction?
I don't have any problem with them updating the scene in line with the fact that the concept of auctioning off women to lusty drunken men might not seem so hilarious in 2018, but this is not a very creative update. It also doesn't look from the videos that they've done anything to tweak the lighting or general show quality to approach that of the Disneyland version and maybe compensate a little for the change.
I agree that the "buy a bride" thing needed to go, but the change really isn't all that funny, it's just kind of bland. I think they could have used a few more women pirates in the scene, except instead of wanting to auction off the jewels they want to keep it for themselves, checking themselves out in the mirror like in these concept images, and the little woman next to the Auctioneer should have been a pirate, but be the craziest one, with a sword in one hand and a bottle rum in the other, covered in jewelry and necklaces, still doing her little "twirl" move showing off all her new bling... they should treat them all like Disney villains, so greedy, selfish, and rotten, that it's funny how over the top they are...
and I really didn't expect them to change the main joke of the scene, which was "there's an auction going on, but all the guys bidding... are only interested in the red head". I think that joke would be even funnier now that she's not part of the auction, they don't even care about the auction, they just want the red head, and then ever time they yell "We wants the Red Head" she fires off a shot across their head like other people have mentioned, I think that'd be hysterical. I do prefer the Disneyland Paris version on the new pirate red head, I guess I thought that's what we'd get in Florida, she seems more "stoic" in Paris, closer to the original version of the character.
You're right though they held on to the chicken line, which was like the least memorable thing in the original scene, instead of thinking about making something new that was just as crazy as the rest of the ride
