I have hatched several in my bra, but only the last day or 2. Usually its after the mother gets off the nest and leaves 1 last egg pipping. I wear a sports bra while doing it, it stays nice and secure. Nights are a little tough. I actually put a tiny thermometer in there and the temps stay pretty warm. And its nice and humid up against skin.
. It is a Muscovy so I have 25 days left to go. Will keep you updated on how he is doing. The shell did have a small crack and a very thin spot so I put a little candle wax on it and is okay. We have already named it LUCKY.
