I visited the 3 chicks next door on October 12th. Today I went to see them again, and they seemed to have doubled in size once more. They are starting to look like chickens although they still make the cute baby chick noise. As usual I picked one up and held her on my chest. It has so much more feather now. She's warm and fluffy.
As soon as they saw me, they just stood in place staring at me. As soon as I stepped away further, two of them started to run around in the small coop and playing with each other. They can make big noise as they jumping up and down in the wooden coop and pecking on the metal heating lamp. The owner of the chicks are planning on moving them outside into a bigger coop this weekend because they are just getting too noisy and messy in the small confinement.
