It does look like the beginnings of a roo . Does it act like one ?
We had a baby roo from the beginning we could tell he was a roo ..by his attitude ..
We would transport them outside when they were babies..we put them in a small dog cage..the hens you could pick up & put in the cage .
Big Bird wouldnt let you put him in the cage normally ...He would have to go in the cage by himself ..As he grew he did become a roo . He died when he was young protecting the flock from a fox
Funny story:
When we 1st had chickens we were very nervous about letting them out . so we put them in the small dog cage ..without the bottom metal piece ..so they could scratch .
They were so small they fit between the rungs & got right out !
Even baby chicks are instinctively wise as the creator made them ..and will scratch right away in the bottom of the brooder .
We put some dirt in the brooder & they started digging .
So The queen is visiting..Better give her the royal treatment !

is this your Mom in Law ?
