We have a 2 yr old mix that has gone broody for the first time. She always get out of the nesting box for food and water. This morning I was in there and she did not go into the nesting box for about 10 minutes. I took her off the nest and took away all the eggs, along with the fake ones in the other nesting boxes. I also put a very large heavy bristle brush (think of a horse grooming brush, but triple the size) and I turned it upward so if she did sit down, she would be on hard bristles. I watched her for about another 20 minutes, and every time she tried to get back in the box, she realized what was in there, squacked, and jumps back down. She does not try to get in the other boxes, so I am wondering, will leaving the brush in break her?
