I have a 25 week old leghorn that spent all evening in the nesting box yesterday, then today at around 9am she went back in and has not yet come out. It is after midnight now, and I'm not sure if I shoudl start to panic about her being eggbound, or some other issue. I can't imagine she is broody. She is a white leghorn. A 25 week old one that has only been laying for about 3 weeks. Her eggs aren't even very big yet. When I try to get close she screeches at me with a weird, teradactyl-sounding noise. I put water in the nest box with her (I'm in Florida, it was a really hot day), but I'm sure she hasn't eaten all day. Any suggestions?
