FEATURE
chicks should be ringed when they are seven days old, but it is impossible to be that precise and so the timing should be taken only as a guide and each chick should be judged on its own merits. You can get variations between the sizes of chicks of the same variety, even in the same nest, but the greatest variation in size occurs from variety to variety. You can expect Normals and Fawns to develop most rapidly of all the varieties and so they are usually ringed younger than, say, Penguins and other non- standards which develop more slowly. It may be tempting to ring a chick too
young, to make the job easier and to ensure you do not miss ringing it. Too often, this can result in the ring falling off and being lost in the nestbox. Once a complete nest of chicks has been rung we discontinue nestbox inspections. Unnecessary disturbance can cause the chicks to leave the nest before they are fully feathered. A chick without many feathers, marooned on a cage floor, can become chilled and, if undetected for too long a period, can die. At this stage of the breeding cycle, a second nest box can be very useful. It can keep chicks warm, prevent them from being ejected or feather plucked by their parents – and permit the hen to get on with laying the next clutch of eggs without having chicks climbing all over her. And so the cycle starts again.
