11 birds on FF x about 10 days. Good things: Poop is firmer--a few that are runny here and there. Waste of food to a minimum. They seem to like it as much as their scratch. Eggs are heavier!~Cooked some eggs for the fam this past weekend and I couldn't get over the size of the yolks. Wow.
Things that are a drawback for FF: A few more dishes and mess in my laundry tub as I brew my FF. Cold mornings/days the FF does freeze for me. I also note that it can stick on my boy's waddles and I've got some frost bite going on the edges of those waddles...but not sure that could have just been from his water, then cold air, too. Need to be more diligent with the Vaseline applications. Had some seasonably higher temps last 3-4 days so FF it is!~ Temps are going to dip down again tomorrow afternoon and I might just save this FF for spring and/or if there is a health concern. Have always had ACV in their water since they were peeps, so we'll still have that going.
Overall conclusion. I like it. Will do it again when it works well with temps or whenever I feel the flock needs it.
