I've noticed a few changes in both appearance and behavior in one of my chickens. Firstly, she's stopped attacking me, which sounds like a win, but I know there is something wrong. Both of the chickens are constipated, but one (Henri) seems more affected than the other (Berni). It's not hot out. They're both laying. Berni demonstrates chicken-like behavior, except for the not pooping. Henri just takes dirt baths, and it appears that she wants to declare war (again, this is normal for her) but just can't quite muster up the strength. Her waddle and comb have become pale. I've checked both ends and nothing seems out of place. Suggestions?
