My girls are now 6 months and used to be little piglets getting bigger every day, now they rarely eat their feed. I have had to wet it down to get them to eat a bit. I'm not home with them all day and I rarely get home before the sun goes down but in the last week I've noticed that in the evenings, when I do get to see them, they seem a bit thinner and their crops don't seem full. I'm not even getting to free range them so they're not really eating anything. Is this common? Oh, and it's the same organic layer feed they've been on the past couple of months. It was hard to switch them from the chick crumbles, so I just mixed it in. Now it's all layer feed. Should I go buy more chick feed and mix that in? Is that messing with the nutrient ratio?
