Yes, they will be inside. I'm putting the brooder box in the den, which is where humans spend a lot of time...that way someone will almost always be in there at the same time as the pets (dogs and cats). I'm thinking of blocking off the brooder, anyway, just to be safe. We have two 7 month old kittens who are curious about everything. They chase my chickens outside. Then I have a dog, as well as my mom's two dogs...mine will be fine with the chicks, she was last year. But my mom's St. Bernard is another story. She wouldn't hurt them deliberately, but she wants to play with everyone and everything. I'm worried about her size...especially the size of her paw...and it going through the screen! I don't have a choice though...I don't have any materials big enough to cover the brooder box except for screen, and I don't have the funds right now to go out and buy anything. I thought the huge box I had was going to work, so this one I'm building is a last minute emergency build!
Like another person said, my girls lay eggs like this too. Nothing to worry about.
Love this gals blog and face book page. Here's something on odd eggs.
