We have 6 chickens, various breeds and various ages.
None are currently laying, haven't for a few months now. Not sure if they will lay again or if they are done. Could be fattened up to meat birds or just pets.
They are all friendly, not jump in your lap friendly, but they like people.
The brown ones we got as chick's so I know they are 2 ½ years old (March of 2024)
The other 2 we got as adults already and I would guess are probably 5 years old
We have a newborn and dont have the time or energy to keep up with taking care of everything.
