this is my 4th week in raising chickens. i have 2 black sexlinks, 5 white rocks, one americana, one newjersy giant(i think), one domineque white rock mix and one domineque rooster. i began with three and they were laying then added the others and now they have stopped. i was told it was stress and the fact of not having light has caused them to stop. woke up this morning and my rooster wasnt crowing like he was, he sounded hoarse. im kinda worried about him.
