An update - 8 chicks have hatched out of 8 eggs. The cat sleeping on the eggs didn't hurt them, maybe helped them. No way to know. But he was sleeping at the end of the aquarium where the eggs were at.An aquarium sets abandoned on a bench in the garage. It has been a favorite nest for any hen that free ranges during the day. One day recently, I saw an egg in it, then as the days went by there were more. I didn't gather them, I wanted to know what hen was laying them. Then, I noticed the big siamese cat was spending the cold nights in the aquarium, on the eggs. Finally I heard the egg song and saw which hen was laying them. Wias out before dawn one morning and saw the cat NEXT to the aquarium. On closer inspection, instead of the black cat I assumed had taken over, it was the hen, sound asleep on the eggs. It will be interesting to see if the eggs will develope. Did the cat ruin them keeping them warm at night, but not during the day, or did he save them from those really cold nights by keeping them warm. I will candle them in a few days and see if they are developing.
And after only having the tiny bantam chicks for such a long time. it is rather nice to have some bigger chicks.
