I have a aprox 13 week old RIR that for the last 24 hrs just wants to huddle down like I would imagine ( first timer) she would to lay an egg. She will eat and drink when I put food by her but wont get up to get it. when I tried to move her by sliding my hand under her she just clucked and stayed there. Might she be going broody or should I look for something else? The other 12 are acting normal.
