I have three young 16 week old Pullets that I hatched and raised And they have now moved in with the main flock last week. When they come in the morning they have a look around they go straight down to a fallen down tree in there very large run and kinda just sit on the brNches sometime grooming sometimes just sitting there ?? Are they ok they are eating drinking and pooing fine. Hhhheeeellllllllllllllllppppppp!!
