I have 2 broodies right now - a Buff Orp and a mutt. Buffy is sitting on 4 duck eggs, Puff is sitting on nothing at all. I tried giving her one of Buffy's but she didn't want it. Guess she figured it belonged to Buffy or something. I put a small glass container in front of her in case she was thirsty during a heat wave last week. She spilled the water out and snuggled the little jar under herself! She does get 1 egg to incubate for part of each day though. 1 of my Australorps gets into the box with her and lays an egg, then Stuff pulls it under herself. Chickens are weird ... Oh, and Puff the Magic Chicken is still taking her job as foster Mum very seriously after 4 weeks. Her babies (runner ducklings) are taller than she is but she still calls them to eat when I put food into the bowl in their cage.
