I have had the same thing, 7 chickens and a guinea fowl were missing, found a roo and one hen near the house, and then 3 days later, another hen came back! She had a bite on her leg and she recovered well! I miss the other 5 and the guinea fowl especially, though.
I have six 3-week old chicks, and I am feeding them chick starter. Should I have stopped feeding them chick starter by now? And if so, could I feed them canola and wheat seeds? And how long should chicks be on chick starter f'or?? Thanks
Chickens are social birds, so I suggest getting another chick to keep her company. Then you will not have as much trouble getting the hatched chicks into the brooder with the silkies as well.
