we hatched our first egg two weeks ago and just got another hatched this morning. we bought a one day old to keep the first new one company and the lady at the feed store said a trick to tell if they are male or female is to hold the chick by the scruff of their neck, hold them, and if the keep their legs tucked up to their chest then they are a boy, if the drop their feet then they are a girl. has anyone else heard of this method? if not, how can you tell what sex they are and at what age? thanks. also i hear that there is a high fatality rate with chicks. we got a plastic file box from the office supply story, cut out half of the top, and put chicken wire over it. the lid has a clamp on both sides to secure it. then we bought a heater, one with just the roof that keeps a steady temperature, then we raise it as the chicks grow (and I can't believe how fast they grow). we have a cheap wall thermometer that looks like a clock that we keep on top of the heater. last, we keep a cloth on top of the heater that we drape over the two sides at night. the temp stays consistent, even with the open top. i am guessing that maybe one of the reasons for a high fatality rate is because of temperature and water going foul. we change the water daily since the step and poop in it. i am not saying we have this figured out, and i am sure we will have ours that die too, but these two things i think are so important. any thoughts?
