My mother's bantams are now laying eggs, at least 2 or three of them are lol, and we're wondering a few things. First of all, can you tell if eggs that have not been set on are viable by candling?
Yes, we have 3 [roosters].
If the hens are with roosters, the eggs are probably fertile.
If you want to be sure, crack open a few eggs and look to see. If you crack open 1 to 2 eggs from each hen and they are fertile, then it's a safe guess that all other eggs from that hen are also fertile. Then cook those particular eggs and enjoy eating them.
Or, if a hen goes broody, just put eggs under her and candle them a week or so later to see if they have chicks growing inside.
She would like to keep the ones in the coop that are viable, and eat the others
They are probably ALL fertile.
but I don't know if you'll see anything at all by candling at that point.
You are correct. Candling will not tell you if the egg is fertile until after the egg has been incubated for a while and the chick has grown a fair bit.
Second, we would like to get our hens to go broody, but don't know how. We think we might try the plastic egg trick. Does this work?
Have nice inviting nestboxes, with a few fake eggs in each one.
Be patient.
Meanwhile, collect the real eggs every day.
Use a pencil to write the date on them.
Store the eggs in the house, but not in the refrigerator.
If any egg reaches one week old, cook it and eat it. (Or put it in the refrigerator until you do want to cook an egg.)
This is because the eggs hatch better if they are not stored for longer than a week before the hen starts sitting on them.
When a hen does go broody (on the nest all night and most of the day, for 2-3 days), then put the eggs you have collected under her, and mark your calendar: chicks due in three weeks!
OK, what kind of fake eggs are the best? Will easter eggs work? What about rocks lol? Are there eggs specifically created for that purpose?
There are eggs created for that purpose. Some are made of ceramic, some of wood, some of plastic. You can also use plastic Easter Eggs, golf balls, some rocks--it just needs to be about the size of an egg, and sort-of round. No poky or sharp edges to hurt the hen.
Also, should we make a nesting box/specific area in the coop for the hen to lay on eggs? Should the hen be seperated from the rest of the chickens while she's laying on the eggs, does it matter?
Yes, make a safe space for the hen to sit on the eggs. You do not want anyone to step on her!
Yes, it is best if she is separated from the rest of the chickens. Seeing them and hearing them is fine, but you do not want the other chickens to push her off the nest! (Yes, sometimes they will.)
Some people make a new pen next to the main chicken pen. Some make one inside the main chicken pen.
If you have a large dog crate or rabbit cage, you could put that inside the chicken pen, with the nest inside it.
For the actual nest, a wooden box or even a cardboard box can work. Just turn it on its side, and have a short edge along the opening (3-4 inches high) to keep the eggs and bedding in.
She will need nesting material--hay or straw or wood shavings or something like that.
It helps keep the eggs warm, and also helps the hen be comfortable sitting there on them.
You say there are three bantam hens. So you might want to set up two or three nests--that way if they all decide to go broody, they don't have to fight over space.
What exactly are nest boxes used for?
Nest boxes are nice for the hen: a cozy, safe place to lay her eggs and maybe sit on them.
Nest boxes are nice for the person: an easy place to find the eggs, and no-one steps on the eggs by mistake.
