Reuse or something new

I m going through what I hope is the list of items retired last year to figure out which I wamt to hunt down and which I can live without.
I then came across fence 42304 and tought I already have this, but iit was not on my list of bought figures. Then I looked into it further and found out I have the fence 42006.
Can anyone tell me if the two fences is different or just the same fence under two numbers?

I have something of the same question with hen-house 42191 and 42421. I know the figures you get with the house is different, but the houses and fences themselves, are they the same?

The hen-house is the same except the colour, - I don't know about the fence, but if they look the same, they probably are, as Schleich is the master of re-cycling

Isn't the hen-house red in both sets?
You are problably right - it just seems ridiculus to give the same thing a new number.

You are right ! The hen-house is exactly the same.
The old 42191-set has the farm lady and light yellow chickens, while the new 42421-set has a nest and darker chickens.
Hen, rooster, house and pen are the same

Sorry ! In my mind I confused it with the rabbit-house/run :

Ahh, thank you. Then I at least have found the right pictures. For some reason I simply can't find the catalouge anywhere in Denmark in paper. It is quite frustrating

And yes, they have a lot of colour on the "new" rabbithouse.
