I have a health question for all of you. On the weekends, my hens get a lot more free range time than they get on a typical weekday- they spent a good 4-5 hours out free ranging on the weekends, as they tend to stick close to the house, gardens, and garage when my husband and I are out there working. On an average weekday, they probably only get an hour or so.
After this, I notice that they tend to have a lot of diarrhea in the following days- it tends to be greenish tinged and contain a lot of undigested grains (from their scratch mix). I'm thinking this is because they're eating a ton more plants and bugs than they scrounge up in their pen on a typical day, and that change in diet wreaks a little havoc on their digestion- sort of the chicken equivalent of going on a weekend bender and paying the price on Monday.
Still, diarrhea is really never a good thing, so should I be worried? They certainly don't look sick- they're bright-eyed, active, hungry, chatty, laying fine. What do you think?
