I have 2 leghorns and 1 bantam buff Orpington. They're all 7 months old and have been with us since chicks. Until recently, they each produced about an egg a day. Within the last two weeks, both leghorns have stopped laying. I've noticed one of the leghorns and the orpington's combs are paler and have shrunken. The other leghorn's comb is pale and has white spots and HOLES in it! Any advice would be greatly appreciated. Haven't had much luck looking online. I realize combs will go pale when they're not laying. I've only seen a few loose feathers around, and besides, aren't they too young for their first molt?! PLEASE HELP!
