I am still confused. My hens seem to be hungry all the time, always eating. There are 16 of them, not quite ready to lay. All big and fat, filled with energy. I've had them all since they were days old. They are mostly RRs, with some Australorps and a couple of leghorns. They can free range on a little more than an acre of thick grasses and lots of weeds. There are many bugs, too. I have been feeding them Blue Seal organic crumble in the evening, and some in the morning to get them out of their pen. I put apple cider vinegar in their water, and they get scraps of food, and cracked corn. There is plenty of grit outside, and they have a wonderful shaded dirt area under some trees where they did up all sorts of things. I have water containers around the property for them. When they see me, they swarm, they always hope I have the crumble. They would prefer the rumble, I htink. If I don't keep the hen house closed when they are free ranging, then run in there and stay until they get fed. They seem ravenous when I feed them, and they will eat and eat however much crumble IO put in. There is never anything left. My silkies, otoh, eat very daintily and they never seem to get to the bottom of their layer food. How much crumble? And how often? They seem to really want it, and maybe I am not giving them enough, although they all look well and healthy. I try to keep them out from morning (around 9) until at least 4, often later, depending. We have dogs who watch the yeard for predators.
