New Chick arrived 2 days ago am worried about water feeder

Hi   Feed the chick crumb dry.  It can go off quickly once it is moinst, and little uns are prone to infections as they haven't got a good immune system yet.

Do you have a Trefle Vert or Agri centre near by?  Normal pet shops are useless for poultry things, you need a big garden centre which stocks equipment for elevage not just an animalerie/zoo.

Even for wee chicks I use a gravity drinker.  You can get them as small as 1L, though 3L is more common - I think mine was about 5 euros.  You can also get a gravity drinker which uses a standard sized plastic bottle (for about 3 euros)

Until you find one, you can use a saucer with a well defined rim and cover the surface with galss marbles to stop the chick falling in and a) getting a chill from being wet or b) drowning

The mum will do most of the work for you, most hens make very good mums. Just keep the feeder and waterer topped up and clean and you and they will be fine  Remember though to take loads of photos as they do grow so quickly
