I bought 4 pullots (hens I hope) last week. 2 barred rocks and 2 araconnas. The biggest Barred rock has a sore on its comb, looks bubbled up and black colored. Today that chicken seemed kinda weak and not active. It also drank a lot of water when I was down there. I then noticed that the other BR had 2 small "warty" spots coming up on its left warble (the red part under its beak, im not too keen on chicken anatomy). I have also noticed that one of the other chickens beak closes off centered, or crooked. Is any of this common? I have been feeding them cracked corn, and one night I gave them some boiled noodles. Thanks.
