Ill try and get some closer pics. If they are all poults - i want to say you all are great. I read somewhere on here about turning a chick over on its back and if it draws both of its legs up close to its body - its a hen. But if it extends both or even one leg its a roo. I picked all these out of a staright run .99 tub at rural king. I must have tested 50 chicks in order to find these that drew both legs up close to its body.
Yes they are 60 days old today - it must be all that cow itch weed growing in their yard that they've been eating that has caused the to grow so large I wont get anywhere near that cow itch but the seem to really like it.
Welcome to BYC! How old is the bird? If it's mature it's a pullet, but I think I can see saddle and wing bow feathers developing, so at this point I'd guess that's an immature cockerel.
Those methods are generally considered wives tales' and have been disproven many times. I'd be inclined to think they either ordered pullets or you coincidentally happened to get pullets.
