Here they are eating my Birch tree that I need to cut down. It's all gnarly and the trunk is split.
I weeded this spot last fall and also this spring and I gave up! I let the girls eat on it for about 10 minutes today. They were easy to spook. I had them out for about 15 minutes today. I will try and let then out every day and increase the time over a few days. I think that I have found a way to get rid of the weeds.
