I have a Buff sitting on a very large nest of eggs since April, 20, 2017. She keeps on laying more eggs, covering them up with the straw, nest keeps getting taller, (now up to 1 and a 1/2 foot), with her proudly on top. The coup is starting to smell, getting hot weather our here, the other ducks (1 male and 4 other females)- do go into the coup at night and lay on the other side of the coup, together, while she spends her night on the "pile" of eggs. my question is-just how long do I let this go on before I "clean out the stink"? Don't want my neighbors to complain-today is May 31, 2017-isn't it time to have duckling?
