My favorite chicken "Aster" is a Black Astralorp and for about a month now she has been staying in her nesting box. I NEVER see her out of it. I do work, and it's a drive so I am out of the house about 9 hours, but my boyfriend is home more and not a chicken person doesn't look all the time, but only saw her out a little at the beginning of this "spell" she is having. She was always a friendly hen, she was the only one that let me pet her. now while she is in the box she puffs all up when i talk and touch her. it's a little scary. I finally got her out and blocked her box...there was no eggs, I thought she was broody, but not one egg. Now she has just moved to another box, and is again not coming out. Is she sick? how do I tell? Or is this how broody hens are?
