Hen Leghorns are slowing dying off?????

[hobbyfrmr]

We live in Northern Utah. We purchased 6 Leghorn pullets in early November. We are down to 2. One was attacked by a dog and lost many feathers, we assumed at the time that between the trauma of the attack and the bitter winter she didn't survive. One was snatched by a hawk. The last 2 are a mystery. They actually have exhibited the same signs as the bird that was traumatized by the dog attack. They just slow down, pretty soon they don't come out and free range like the rest and then they end up just sitting on the floor of the coop. They stop moving, you can actually touch them and they just fall over. I have 3 older sex link hens and they are completely fine. Did I happen to get some chickens that have some bad traits?

Give us some more info:

Age when you purchased them.
When did you notice symptoms?
You can also go to the poultry site.com and look up diseases by symptoms.

Isolate sick ones from the rest of your flock!

The signs are very few. They seem detached/depressed, very subtle, the last one we didn't even notice. Then they quite coming out of the coop. They don't roost. Their combs start losing color. They don't eat or drink. Then they just stay in one position. It is almost like their legs give out on them and just stay curled up. They will just fall over if you touched them. We are thinking maybe they just had internal injuries from the dog attack back in November/December. Three hens were attacked. These 3 that have died could be the three. They are just now a year old. They started laying about 1 month after we got them.

Could possibly be several things-with that little bit of information, I would guess worms or mites/lice. Strictly a guess, but without knowing anything else, that's what I can think of.
