Christian Posted February 22, 2010 Share Posted February 22, 2010 I think it does with crocodiles, but no idea about chickens! Good ol' Mr Attenborough! Quote Link to comment Share on other sites More sharing options...
tom123 Posted February 22, 2010 Share Posted February 22, 2010 I think it's a myth but a similar theory is that hatching earlier in the year produces more boys but the only problem with doing research to test this is that you have to decide what 'earlier in the year' means in the hatching year Quote Link to comment Share on other sites More sharing options...

TAJ Posted February 22, 2010 Share Posted February 22, 2010 I read something that in colder weather/winter hatches are more likely to be males. Tracy Quote Link to comment Share on other sites More sharing options...
Lewis Posted February 22, 2010 Share Posted February 22, 2010 I think younger hens are more likely to produce more cockerels, and earlier on in the year you get more cockerels ... something to do with competition, and nature produces more males so that there can be at least one with a competitive advantage I think the temperature thing is reptiles ... not sure how it works though Quote Link to comment Share on other sites More sharing options...
Redwing Posted February 22, 2010 Share Posted February 22, 2010 There has been some experimentation with this on the practical Poultry forum, results were inconclusive if I remember correctly Quote Link to comment Share on other sites More sharing options...
