Hi, I am a first time chick owner and I am not sure how old my chicks are. I bought them from a farm store on March 5th, so I have had them a little over a week, but I don't know how old they were when I bought them. I bought 2 Rhode Island Reds on March 5th and loved them so much I went back for two more (this time the box said Buff Orphingtons) on the 9th. They have different levels of feathering so I am not sure. I have searched the internet and can find no pictures of chicks at certain ages. Any help?
