My amazingly broody silkie, elvis, is sitting on an egg and won't get off of it even to eat or drink. We take her out every 2-3 hours to get some excersise. She'll drink a little but won't eat and we have to force her to walk. The egg should hatch on the 15th but were not sure she can make it that long. Please help!!! I know silkies are known for there broodieness but this is ridiculous!!!!!
