how much do chickens cost /best ones for most eggs

[Straight Shooter]

I have warrens , good layers, they drop off a bit after 3 years, mine are penned in , 20 mtrs by 3 mtrs , we have loads of foxes about here, they would not last a day without the fence, I feed them Layers mash and mixed corn ..all the veg peelings grass cuttings and any other scraps from the kitchen. I am down to 4 birds and I intend to move the New hens and cock into a luxury condo within the next 6 weeks .....closer to the house... some ducks been promised by a farmer friend , also on the agenda are pigs and goats for the acre I do not use ( that should clear the ground double quick ) but I will have to fence off a fair bit around the boundry....need more funds for that , as well as more time...... both are in short supply ...the good news is I have most of the straining posts.
