Used HN in week two with chicks, they picked it up with no issues what so ever. Tapped the nipple they came flying over and took it from there. Love this system.
05/15 - used this with five day old chicks and they picked it up right away.
06/04/15 - introduced waterer to chickens hatched by a broody Cornish. The chicks were introduced on day 2 and on day 3 I saw them actually using it. Good job mom for teaching them so young. We do not heat the chick waterers as we don't have chicks In the winter.
