DH went to do a last check in on our emo chick, Xena, tonight and said their was a little mouse that scurried across the floor, fairly close to our girl. Now, I'm freaked out. She is the only one in the BHC (Brooder Hospital Coop). It's pretty small with only 2 nests and no roost bars, plus she is setting on 9 eggs. DH said it was small, a field mouse, and that we don't have rats here..... well, why was it IN HER COOP?!? She had a small container of food in her coop that has been removed, as she should be hatching eggs within the next 36-96 hours, and we're prepping fermented starter feed for the new nuggets. She had a water dish in the minor run however, we removed that as well. We put a nipple waterer inside the coop and added some electrolyte powder to it. Is this concerning? Weirdly, I fear it eating her eggs while under her.... or even eating HER while she is in the *broody daze*.
