Interesting, a week old and barely a hint of feather. How old are they when they fledge?
By 3 weeks old they'll be starting to come out of their nestbox. They grow incredibly fast. I had to hand rear two chicks from two weeks old at the beginning of the year because their parents abandoned them when the other batch of chicks from the other pair fledged. The parents of the younger chicks decided it was easier just helping take care of the older ones. They were the first chicks I raised and, despite being cold and starving when we found them, they survived. I've raised quite a few birds since then!
