Just my impression from what I read. I don't have direct experience w birdbath de-icers, they might work great. Sounded like they will keep the water in a bucket open, but water still freezes in the nipples if it gets too cold, even the horizontal ones. I figured bc the cheapest birdbath de-icer is about the same price as a decent small aquarium heater, I'd try that first. Definitely let us know how ur system works. Comparing notes will help us all.

.
Btw, how r ur other projects going? How r ur JGs doing? I just processed some roosters, same age
Yup comparing notes will help us all, still looking into all options, need to decide soon, like it or not winter is a coming!

and I don't want to be busting ice again...
White JG doing great, growing much quicker than expected. Had a couple deaths as chicks, not used to that, few with their (sandhill) packing peanuts, red sussex. Three sussex and two giants died right off, wasn't happy, but survivors very hardy and healthy. Have three giants non breeders, two yellow legs and one no tail and bushy leg feathers, looks like a rumpless aruacana crossed with a fluffy butt orpington. Others are amazing! I can pick out the breeders on the red sussex, giants they all look so good I'm building a tractor/coop bachelor pad to keep them till spring before I make any decisions. Will work out great for my giant silkie project, have a huge roo from
TSC, four pullets laying daily! and one huge roo!
Silkie roo will be with the girls till spring, hopefully they lay by then and we can have a hatch.
Will be later spring before I'll be hatching pure white giants for capons.
My opinion on good capon breeds? not what I'm doing, Lol, I just want the biggest. I'm kinda glad Sandhill sent me those red sussex packing peanuts even though I only see two pullets and three cockerels as SOP, rest have way to much black feathering in the breast. They grow fast like New Hampshire's, but are a ancient breed so I'm glad I didn't get the Langshans that grow super slow like the giants.
IMHO NN Turkens are the perfect meat bread for caponizing, they grow great and lay great and are somehow hardy to cold weather even though the have a naked neck?
You've heard the breese is one of the best tasting chickens? And the Barbezieux the third best, better than the breese, a roasting chicken where the breese is typically poached? (According to the French) Well I wondered what was the #1. Took some time, couldn't find any thing in English, all French, but I finally found it, did some google translate, not a strange weird breed never heard of, it was Poulet Rouge, naked neck chickens!!....we have them here...
Naked neck turkens and new hampshires would be the best picks for capons in my opinion.
Edited to add, Delaware and light Sussex are also good picks IMO.
Green Fire Farms had a good writeup on Bielefelders for capons
