Terramycin and laying hens

[msblackie]

I've noticed the girls have been sneezing a little. THey have dry litter and are able to get outside everyday. they are on layer crumbles. Their egg production has dropped dramatically this last week. We used to get about 20 eggs a day and are now getting 6-10 eggs a day. I was going to put some terramycin in their water until I read not to give it to birds that lay eggs for human consumption. Could I give terramycin for ????? days and toss all the eggs we get for ????? days?
How many days should I give the terramycin and how long after we stop the meds should I feel safe in eating the eggs.
Any help would be greatly appreciated

* I have never seen any info on how much (if any) really crosses into an egg-- but, I just feed them to the dog after using stuff, usually, or back to the hen (rarely), until she's been off it for 1O days or so.

thanks for the quick response. Should this along with a good cleaning of the coop take care of the sneezing????
would this account for the decrease in egg production. I thought it might be because we suddenly have had a few days that were in the 60's at night and 90's during the day.
IF they are molting wouldn't we be seeing a lot of feathers in the coop and wouldn't it be very noticeable on the hens???
