We recieved five ducks from a friend who (very last minute) was moving out of state, three went to a neighbor and the male and female stayed with us. I have not seen her lay an egg (or found any on the ground of the coop) but noticed yesterday she seems to be very "rear-end" heavy and wondering if she could be holding them in? If anyone knows if this is possible or there's' something I can do, any help would be great. They have been in the coop with our chickens sense we got them (didn't know we would be asked to take them and still in the middle of winter here ) not sure what to do.....HELP!!
