Hi all, My Rhode Island Red is 33 weeks old (8 months), and laid her first and only egg at 29 weeks old on Nov 1st. She is not the youngest hen, but I belive she is on the bottom of totem poll. She doesn't get picked on or tormented by other hens or even the rooster for that matter. We live in Central Florida and temps have been getting down in the 40's occasionally and it is their first winter (I know its not cold for everyone ). I'm pretty sure these birds can handle these temps with no problem. We have had young chicks around them (separated by a pen) from the time the chicks were 6-13 weeks (now), and this hen is by far the meanest to them. She will go out of her way to chase them and try to hurt them. She will follow them around the outside of their pen trying to chase them. She is not mean to any humans or any of the other chickens.Very frustrating that my other 2 RIR's are laying regularly and I get nothing from her. I have seen her in the nesting boxes trying to lay, but there is never an egg. Has anyone ever had a hen with this problem? HELP!
