I am a first time chicken owner, so this might seem funny to most. While I have been reading that the birds will grow fast. It just seemed that we would see the progress over time. Well, yesterday I went to check the water and make sure the food was good, we have Chickens! The chicks are now Chickens, it's like they just changed over night! Fluffy to feathers and one of the Roo's is starting to try and crow....So funny to hear.
