Nutrition; Problems That May Arise During Incubation - river systems ET 12 Notice D'emploi

9B – NUTRITION
Normally the chicks start eating and drinking from their second/third day of life. Put a drinker and a feeder for fine fodder in the box/pen. We
suggest the following products:
Drinkers:
- art. 137: siphon drinker - capacity 1,5 litres in polypropylene (suitable for all chicks, even small sized ones)
- art. 138: siphon drinker - capacity 3 litres in polypropylene (suitable for bigger sized chicks – not quail or pheasant)
- art. 137/A: Bottle-holder drinker for chicks (suitable for bigger sized chicks – not quail or pheasant).
If you use other drinkers, make sure that the basin is not higher than 3-4 cm, otherwise the chicks may get wet or drown. To prevent this, we
suggest you put some pebbles inside that will attract them towards the drinking water.
Feeders:
- art. 296: polypropylene tray Ø 24 cm
- art. 120: galvanized feed trough with grill L=0,3 m – or L=0,5 m (art. 121)
- art. 120/A/R: plastic feed trough with grill L=0,5 m
We suggest you sprinkle some fodder on the newspaper sheets too.
