I have heard that chickens can actually lay multiple eggs in a single day. Is this possible?

I know that leghorn hens usually lay eggs every 25 hours or so (for an annual total of about 280-320), but can they actually lay more than one egg in a day? If so, how is that possible?

anyone have any ideas? –  ServAce85 Apr 25 '11 at 15:38
    
Could you be confusing two eggs with double-yolked eggs? –  Oddthinking May 12 '11 at 14:03
    
talk about rare, our Rhode Island Red "Big Bird", who has been laying for about 2-3 weeks now, went into her box this morning and was in there for quite some time. When my son noticed that she vacated the coop, he went to retrieve the egg. Much to our surprise, she layed 3 eggs. Is this possible. I checked in the morning and there no eggs in the box. The other chicken we have are 2 white Delewares (white eggs) and one bantam red (still too young to lay). Is this possible?????!!!!!!! –  user4413 Aug 8 '11 at 18:25
    
@Oddthinking the question was asked exactly as I have heard, but I'm interested to learn how common double-yolked eggs are if you wouldn't mind sharing. –  ServAce85 Aug 10 '11 at 23:35

I love the wording of your comment, that politely suggests that I know exactly how common double-yolked eggs are, and that I am keeping that info to myself :-) Alas, I am a city boy, and I have no idea! –  Oddthinking Aug 11 '11 at 1:10

If there are chickens that lay more than one egg a day, they are very rare. The cites I can find indicate that most chickens will lay about one egg a day at the prime of their egg-laying production:

How many eggs does one hen lay per day? This depends on: the time of year; the breed of the hen; the diet of the hen; the age of the hen; and, how the hen is looked after. Most of the standard breeds of chickens that have been selected through the years for egg production will lay between 180 – 320 eggs per year for their first year of laying. On one extreme, there are records of hens averaging an egg a day for over a year. The rate of laying tapers in the second year and beyond, until it may only take place during the spring. Some of the breeds that haven’t been selected for egg production (selected for show, or other qualities, instead) may only lay eggs in the spring and early summer. Appropriate feed mixtures also stimulate egg production. Provide 14 to 16 hours of light for hens to lay regularly. One hen can only lay, at the most, seven eggs per week while most chickens lay fewer. A hen which lays one egg every day is a very good layer.

And this:

Egg producing chickens have been bred for maximum egg production rather than meat yield, and can produce up to 300 eggs per year. These chickens are usually of the White Leghorn type and lay white eggs, although brown egg layers are also available. They have a mature body weight of 1.8 to 2.0 kg (four to five lb.). Dual purpose chickens are raised in small flocks for both meat and egg production. They are smaller than commercial broilers, but reach a mature body weight of approximately 2.5 kg (5.5 lb.) for females and 3.0 kg (6.5 lb.) for males. The hens will produce 200 to 250 eggs per year. Typically, the eggs are brown. Available breeds include Rhode Island Red crossed with Barred Rock, Columbian Rock, or Light Sussex.

It looks as though one per day is the best you can expect. Biological systems are prone to having outliers far from the mean, so it's conceivable that somewhere out there is a chicken that can lay two, but that would definitely be unusual.

From the chicken my parents used to have I can say that Young chickens (to some extent old ones in spring, after winter pause too) layed very big eggs, often with to yolks in. –  No longer here Apr 26 '11 at 9:01
