I am new to the joy of chickens, my flock is only 4 hens. The girls have recently moved from inside to the outdoor digs just 10 days ago, and are allowed to strutt their girly stuff around the back yard about 5 hours every afternoon. They are happy to get out in the afternoon and happy to return to their home when it is time. They come when I call the chick chick chicken but, only Houdini comes to her name. I think the other 3; Nugget McNugget, ColSanders McNugget and second breakfast McNugget don't find their names all that amusing and refuse to respond. (We are also care takers of young adults who found naming them too fun). A freind brews beer from organic hops, barley and Malts. Is it safe to feed the girls with the Detritus, spent hops? I haven't read anything here about the subject, and suspect the girls will love it. My concern is that they are still young, only 9 weeks old, and want to be a good flock partner. So, what is the ruling? Give the girls the spent grains? or not... Thanks in advance Any assistance provided would be wonderful and graciously accepted.
