O.K.,......Here's the thing.
I have predatory animals of all types and flavors where I live.
Do you have to coup them at night?
Do they make a lot of noise?
How long do the eggs last?
How many will they lay a week?
Looks like Jimjimmers answered your questions well,
as to wether you want eggs or chickes to eat?
For eggs you want layers, for eating you want another breed of chicken, you can eat layers, but the meat is tougher.
One can also extend how long an agg will remain eatable by coating the egg in oil, as this provides a barrier and lets the egg remain fresh for up to 6 months.
My chickens are very quiet, except when they see me open the back door, then they all run to the fence of their pen, wanting their greens, they expact them now when ever I go outside, a bit spoiled I guess.
We do have the chicken run covered top side and bottem, and it is a large pen, safe from preditors.
It took time to build, but was worth it, as we have peace of mind for their safety.
We also have a warming light, colored red to keep them from pecking at each other, the light goes on before dusk, and they all line up in order to enter the chicken barn, it funny to watch, as if the wrong chicken goes in before its trun, they all leave the barn and start over again.
I guess that is where the saying pecking order came from.
One quick question to any that might know the answer?
Can chickens eat honey suckle flowers? One fell into their pen, and they fought over who was to eat it.
If it is safe for them? I have pleanty and would love to give them this treat.
God bless
