Hello

I am looking for advice.
I have a coop that is really a rabbit hutch, with the dimensions of 6 x 2. I have one bantam cockerel and two bantam pullets in there. Today is day 18 for my one pullet. Well, my other girl just started laying eggs when my broody started to set. She has now decided the past few days to "egg sit" while my broody got up to do her business. She is now broody and did not roost tonight!
I don't know what to do with both of them in there together. Also, would it be too early to give her three eggs if they will hatch soon?
