I spend a lot of time with my girls and feel as if my wyandotte is showing signs of going broody. I've had chickens for 3 years and this will be my first. She's spending more time in the box hissing but not sitting all day yet...she is making more strange sounds, puffing up, and bald on her chest. What am I in for?? I don't want chicks this year so she won't be getting any eggs/chicks. I'm fine if she wants to sit in the box all day but it is HOT in there and I'm afraid she'll scare all the other hens away from the nesting boxes.
