I have a couple cockerel confined singly in pens for purpose of taming for later handling. They have been provided a free-choice access to a complete feed mix for all but about 2 hours each morning and the night time. The trough I use to collect and store rainwater is nearly covered in the stuff so I have been taking it out in major hand fulls and putting it in the waterers. The cockerels are eating it in a big way. By volume it is mostly water yet they seem really partial to it. I am having a hard time keeping the duckweed present owing to how fast they eat it.
