My husband went to the barn and luckily he did. coming out was a weasel with a young hen in its mouth. He stepped on the weasel to make it let go of the hen. The damage is bad. the whole top part of the thigh is split open. we can see the thigh bone. (the big part). The skin is split about 3 cm. 1 1/2 inches. We have no vets here... Do I sew this skin together or just bandage it up with anti-biotics... ????
