This is actually the first time I have decided to letone of my hens go for a second round. So what is the best arrangement for the nest box? The two chicks in there are 3-4 weeks old now and I caught the pair having a bit of budgie love today so I suspect they are starting to think about round two. The nest box is currently on the floor of the cage with the end open as the older chick is starting to poke her head out of the box and has jumped out once already. Is it best to put the two current chicks into an open topped box(like a shoe box or something) on the floor of the cage for dad to feed and put the nest box back up or should I leave the chicks in the nest box?

it depends on mum. If she is happy, leave them in there, if she looks like she is getting aggreive, get an old ice cream container, put shavings in it, and put it on the ground. You do need to snure that Dad is feeding them, and not just mum in the nestbox.

Should I leave the nest box on the ground or put it back up? Just worried about the fact that the babies are starting to swan dive.
