My Welsummers are probably going to finish out about the size of emus. That's all I can figure out. I keep going to the feed store for more and more feed. 'Just keep feed in front of 'em at all times'. They appear to be growing like mad. Is it possible to feed them too much? They are acting like ravening beasts. I give them their regular feed, and sprigs of alfalfa,, grit, plenty of water. I think they are six weeks old now. They are the most awesome chickens ever. I'm just putting in the posts for their permanent coop.
