The other day I let the donkeys out into the pasture, then allowed the chickens out into the donkey yard (as is the new normal routine). I was doing some clean-up and left the hay aisle open. Golda saw her opportunity.
If you look carefully you'll see her at the bottom of the straw bales on the right. She started working on her nest immediately.
The other three were a little upset, standing on the other side of the aisle fencing. Golda didn't seem pleased to have them there and was making an aggressive sound I've not heard before. I left her alone, and sure enough, there was an egg.
So, clever me says, OK she must want straw bedding (I use shavings). I cleaned out a nesting box, stuffed some straw in and she wouldn't touch it. For days. No one would. Out comes the straw and back in go the shavings.
Yesterday we went through the same routine. Hay aisle left open = 1 egg.
