My sister went to set up her brooder the other day, looked inside and found this:
25 eggs! :gig
She had it covered but there was a little 4x4 opening top and this little girl could squeak in.
She candled and didn't see any development. So she gave her the warmest 10 and took the rest away.
I have them in a large cardboard box at my office. I would put them in my small coop but I have eggs in the incubator and I'm hoping to put everybody in together if any hatch, so I'm just going to keep them down there until hopefully that happens. They have a heat plate, and I use puppy pads for...
I would pick a good broody over an incubator every day.
You might want to let her set for a few days and make sure she sticks to some dummy eggs first.
Cute as they are they are very stinky - had some in my garage for a few weeks for a friend and never again (she got rid of them soon after she took them home too)
Most Mamas pick up their game when they have babies to protect.
I've got a whole basket of little brown eggs sitting on my counter just waiting for somewhere to go...
