BREEDING FOR PRODUCTION...EGGS AND OR MEAT.

[stryker]

Now, there just may be something to it beyond fever and such. Aspirin works by inhibiting prostaglandin production and prostaglandin works on many different levels in the body....if I were going to lay money on it working, I'd say it would be more likely to work on the hen's hormone levels or vascular constriction or dilation of her brood patch, rather than on her hypothalamus to prevent a non existent fever. But, I could be wrong....it happens all the time.

The diversity of receptors means that prostaglandins act on an array of cells and have a wide variety of effects such as:

• cause constriction or dilation in vascular smooth muscle cells
• cause aggregation or disaggregation of platelets
• sensitize spinal neurons to pain
• induce labor
• decrease intraocular pressure
• regulate inflammation
• regulate calcium movement
• regulate hormones
• control cell growth
• acts on thermoregulatory center of hypothalamus to produce fever

Another way of breaking a hen from going broody is to save a dozen eggs and plan to put some under her the following day. She will be off the nest and not want anything to do with sitting. I guess the eggs are going in the pan. She was not on the nest today either..

Did you worm them before they started laying? If not you may be seeing damage from worms.

Otherwise, only hatch eggs that look good to you.

No I didn't worm them yet, but it's only the 2 Buckeyes from one line laying gs like this. None of my other hens are laying weird eggs.
I was just getting around to worming them as we've only just had a hard freeze. I haven't had chickens for years, and these are 7 months old, could they be wormy? I haven't seen worms in the poops.

Isn't that just the way things are with chickens??????????? Too true.

It is possible--Pullets coming to point of lay are susceptible to damage and since the egg shell gland is at the end, it is more likely to be damaged.

With all of that said, I have seen eggs start out like that and then get a lot bigger and rounder in a couple of months.

Wait and see what the shape is when she is laying full size eggs. They may be fine.

Worm them though.

Oh good, I do hope so. And I'll get to the worming right away. Thanks!

Does the egg change shape if the birds need to be wormed?

The pullet is still developing when she starts laying so the effect is then. Worms will not hurt the egg laying tract as much when they are older.

The one time when you should definitely worm them is before Point of Lay. That is different by breed. Early layers would be at about 16 weeks. late starting breeds can be more like 20 to 22 weeks old.

Not worming them at that age can also hurt egg production--some pullets will never lay an egg if the tract is damaged too much.

I need some advice. I have a few Buckeyes, and they have just started laying eggs. The size is fine, but the shape is terrible., long and thin. How do I fix this? I have no idea how egg shape is inherited (posted the question on a genetics thread and got no answers, and I don't have access to anything but abstracts from papers in journals).
If I cross a hen that lays a long egg like this with a rooster from a hen that laid a "normal" shaped egg, will the eggs from the F1 pullets be intermediate in shape? Or will one shape or the other be
dominant?
The egg on the left is from a Buckeye pullet. All the hatching eggs were kind of ugly, long like this, so it's clearly set in the line. Other lines of Buckeyes have better egg shape, I'll need to get some of those. Depending on how this trait is inherited will decide whether or not I breed from this line at all. Egg quality is important to me.
The one on the right is from a sex link mutt pullet (unknown cross). This egg has a "perfect" egg index of 74 (width divided by length x100) .
The eggs are a bit distorted by the wide angle cell phone lens. Does anyone have experience with breeding hens laying atypical eggs?

Perhaps eggs like these long ones could put some length and height on your birds...

Seriously, I will soon be in touch.

I read in one of the other posts...I'll have to find it. Their theory was the long eggs are pullets and the round eggs are cockerels. Care to disprove the theory?
