Thanks for responding bro! Glad to hear from you again!
You make them sound like the perfect role model chicken! My hens, especially the big fat one, eats like there's no tomorrow. She's also an irregular layer sometimes going for 2 days without laying. As this is my first time keeping chickens, I didn't know much about them so I just bought what was available locally. The big fat one is a Rhode Island Red x Australorp. She's probably a good 3-4 kg (6 - 8 lbs) as I need some muscle flexing to catch and lift her as she's so strong and chunky. Good as a meat bird but I'm only rearing for eggs. The rest are also large Australorp crosses and they went through a 20 kg (44 lb) bag of feed in 1.5 months! My hens don't like to be touched either.
I've been having my fair share of problems with them with disease after disease. If all hens were having issues like me it'll scare away anyone from rearing chickens. I'm pretty sure it's not me as I recently bought a Roo and he hasn't presented any sickness so far (*fingers crossed!*). The Roo was purchased from a separate local breeder so I reckon it must be the hen breeder I bought from.
Anyway you're probably getting bored reading all that. There's a commercial breeder that takes orders from various local feed stores around the central west region and then delivers hens to them where customers will pick them up from. They sell Isa Browns and I thought maybe they were as good as Leghorns until I read your post. They've also started selling Leghorns but are unfortunately crossed with Australorp and I don't want another food hogger.
Guess I'll just have to keep a lookout for pure white Leghorns in the future. Thanks again and take care!
