So my Ancona duckings are still receiving bath time indoors till the weather warms up and i get a swimming apparatus set up for them outside and they have this strange behavior when I have to change out the water and I turn the faucet back on. They all sit back sorta on their hauntchs * if you can call it that* puff out their chest and pull their head tight against their body? I'm posting an image as an example at the bottom. They seem to do this any time the water is running until the tub fills to their desired depth and i turn off the water... I can't find any info about this anywhere online or this forum though. Is this a defensive pose? or is it relaxing? They are only 4 weeks old.
