i have a few questions. when is a chick no longer a chick? thats just a curious question for me. . and where can i go to find out how old my chickens are, other than the breeder (?) I have 2 chickens. the rir has started to grow a comb and it is growing fast. On july 7th it was hardly there, and it sure is noticeable now !! My other chickens' is growing but its not as red.. could be the breed? july 7th july 24 i know my chickens are at least 9 weeks old but not sure how much older than that they are.
