It's winter here of course so the girls haven't been able to forage and roam the yard and even when they do everything is dead so there aren't many options for fresh greens. I've been giving them kale, spinach, etc. about every other day because from what I've read those foods are still considered a "treat." I'm wondering though how often can my girls have greens? I would think since in the spring and summer they'll be eating grass, bugs, weeds, etc. all day that I could give them greens every day, but I want to make sure! Thank you!
