My 2 black sex links and 2 production reds are 16 weeks old today. my PR are squatting and their combs are really reddening. One of my BSL had disappeared several times right when we need to put them in...Last night I searched an hour for her. I am pretty sure I went through nettles and poison ivy and I KNOW I went through thorns, (OUCH). I think she may be scouting for a nest....I noticed her wattles suddenly exploded. Can't wait for eggs!
