Really Worried - woodchip

I put down a new layer of woodchip yesterday, which I know contains eucalyptus but I'm not sure what else.

The hens seemed fine with it yesterday, but today they won't go on it much at all. One hen is happy digging through it, but the others are very subdued and won't go out of the run into the garden where the new woodchip is.

They all ate some rather old sunflower seeds yesterday too ... but it wasn't mouldy or anything.

Have I poisoned them?

I will get out there and take off the new chippings, but I may not manage it all today - it half killed me putting it all down yesterday!

Hi, ive done what Joy has done and googled it.There are some posts on the omlet site where some of their members have used it with any ill effects!
Maybe its because its new, mine go mad if there is anything strange or new, or maybe its a bit sharp on their feet?.. not much help i know, but i cant imagine any fumes from woodchip to be harmfull out in the open air.

Rain makes some of mine miserable
