Hey everyone! Newbie here, and 5 days ago I got my first two little peeps. I'm guessing they are about 3 weeks old now. I've been keeping their brooder around 70-75° (the temp in my bathroom) and fashioned this mama hen cave from chicken wire, a heating pad, and press n seal, which they go in at night to sleep when my bathroom gets to about 60-65° (I lower the heat in the house at night). All of that in mind, would it be problematic to add another chick at this point? We've decided we want 3 altogether. Any help/ advice would be great! I've attached some pictures of the girls and their setup.
