lamb ears plants

I have bought a couple of lamb ears plants a little while ago from the Kew Gardens nursery (they were outside when I bought them).
They have been doing very well so far indoors on the windowsill, semi shade position I would say, growing very well and strong.
Then i have decided to split the plants into different pots giving each its little root.
I have put two plants outside and kept one inside to experiment which spot they prefer.
Now the two outside which enjoyed quite a lot of sun and they have been watered regularly, they are super floppy with a couple of leaves yellow!
Do they dislike the sun so much or could the floppiness be only the first impact with the outside air?

 

Probably related to them being split it. Might have been better to have kept them in pots for a while, after splitting, to give them time to get going again. Easy enough to move pots out of the heat of the sun, and in the house (for example) they don't have any wind to dry them out ... and so on.

Splitting them, outside, in Autumn would be less stressful for them. For now just keep watering the ones outside so they don't dry out, and don't have to try hard to find water.
