Funny you say that. I have 2 cuckoo marans that came from Jax (my niece's Easter chicks a few years ago). Cackle birds I think. They both lay the wimpiest light brown eggs and go broody at least 3 times a summer. Makes me want to never have one again.Jax just 8 blocks from me will add to their order for individual needs. Not so happy with the ones I have gotten from them though. Not a single good layer in the bunch.
I've raised about 150 chicks from FS. I've had 8 turn out to be roosters and only one not the breed I bought. (white cochin instead of light brahma. Easy enough mistake if they fall out of the brooder).
