Hi this is my first post and I have a big question. I have 3 hens & 1 roo about 2 mths ago they quit laying and havent layed since. thie weather here is not that bad (east Tex) I have been giving them lay pellets and oyster shell but no eggs I even theaten them with the boiling pot and squeezing them with no luck. I have let them free range and cooped them still nothing. Any ideas???
