This fount is specifically designed to keep your baby birds from drowning. It has a very narrow drinking space which will not allow them to drown in their drinking water. This narrow opening will also prevent the baby chicks from soaking themselves. Plastic fount base threaded for standard mason jar. Fount is 3/4" high and 1/2 inch wide to provide adequate drinking space, yet it prevents drowning.
Do not come with jars. These work great with our plastic jars. The large plastic jar holds 58 ounces and the small plastic jar holds 1 quart. These plastic jars do not break like glass mason jars when the baby chicks knock them over.
