I have some questions to put to the brains trust. Firstly broodies; when your broody stops being broody, do they stay off the lay for a while?
The short answer is yes. Of 9 hens 3 have gone broody recently & are all off the lay.

Secondly, thoughts on vaccination.
There are 2 schools of thought out here on vaccination. I'm not a scientist so most of the arguments go over my head but roughly:
1. If you vaccinate your flock can still be disease carriers & increase risk by the germy things mutating & becoming harder to eradicate ~ nope, not very scientific of me.

2. Don't vaccinate & let natural immunity work for you but you risk wiping out an entire flock if disease breaks out. This is why the strict quarantine rule with new birds.
If you have a FB page look up Johnry Ramos, specialises in Pekin Bantams, & has some excellent articles on anti vax.
Having said that my birds are vaccinated because that's what my breeder does & it meant I could take a reasonable risk with no quarantine with my last buy. If I ever buy elsewhere that simply doesn't become an option. They will have to be quarantined!
