Last night my youngest boy asked me what we were going to do if all 5 hatched because we're only allowed to have 3 more. Ooops. The child knows the law. I had to explain the chances of all five hatching wasn't very high, and, if they did, they would live in the garage until they were big enough to go outside. As long as they were tiny enough to live in the garage, having 5 more would be OK. I also told him we would have to give away any roosters that hatched.
Dawn.... just curious why you can't hatch in the house any more? I remember reading that a while back and it made me nervous because I was afraid it was going to stink or something. So far, so good. They don't stink... yet. I have my incubator on a book shelf out of the way, so it hasn't bothered DH at all and the kids forget it is even there. DH is actually finding the process fun. When I told him I was going to candle the white one last night - he came into the bathroom to look at it, too. He thought it was pretty cool.
I did weigh my eggs before they went into the incubator. I haven't weighed them since. Maybe I should do that to see if the others are developing.
I told all the kids from the start that the likelyhood of all the chicks hatching was very low. We talked about some of the reasons, candled partway through, etc.
My husband does not like house pets - and I didn't really ask his permission with the chicks.

The hatch itself wasn't stinky at all - but the chicks in the brooder was. And more of an issue than the smell was the dust all over everything!
Since we have plenty of hens willing to go broody, I made a deal with my husband that all future chicks would only be broody-raised and sold the brooder & incubator.
