Hi guys
I have recently made a new pen and had the chickens in the hen house until I had finished making it secure . I let them out yesterday afternoon when after 3 hours my neighbour said, oh you have let your chickens out, I noticed you where buiding a pen so i put roundup on all your weeds for you to help you out!!! I cant believe it, he said he put it on the weeds about 3 weeks ago, however the weeds and grass are still green with a yellow tinge on some. What should I do, the chickens where out all day yesterday, is it safe for them to be on there and eat it our am i facing my worst fears?
