I also have a 3 week old peachick that I incubated and has become very clingy. Today I had the two, two week old silkies out sunbathing in one coop and the peachick the other part of the garden in a covered pen as soon as I went over to the others what a noise!! He/she, now called Blue lives meal worm and chopped hard boiled eggs. Blue knows instinctively how to preen , peck sunbathe etc. The only thing is keeping Blue under the brooder in our sitting room. Which is now getting quite smelly. At what age will Blue be able to stay the night in the newly built coop??!
