Around the three week point, the first juvenile feathers begin to poke through the down on the breast. The chicks continue to rest on their tarsi much of the time, rather than standing on their feet, but this balance shifts quickly in the days to follow.
Our three little darlings are becoming more and more fat. And they should. In this stage they seem to be nothing more that big bellies. Laying on top of eachother being very lazy. And least it looks like that. Babies need a lot of sleep, including these 3 babies. Sleep and food.
Look at the flightfeathers how they appear around the edges of the wings. The feathers are protected by the shafts they grow in. They will break off eventually.
Thfeathers that are growing are connecting by bloodvessels that feed them. They are very sensitive. Around every feather is a matrix of nervecells as well as musclecells. In this way it is possible for the bird to move each feather seperatively as well as specific ones together.
The primaries and the tailfeathers are the most important ones to be able to fly.
In this stage the feathers grow a few mm a day!!!
