Hi everyone, its been a while since I last posted anything. I have had 6 hens for just ver a year now all laying well except one which is always broody. I asked my local farm supplie store if they sold any fertilised eggs and the store assistant gave me 4 fertilised eggs for free. I put these under the broody girl and let her sit on them for 20 days. I now have 3 beautiful little chicks. The 4th egg was not fertile. Sorry about the long winded intro but my question is do I vaccinate the chicks or not worry. They are 3 days old now, eating and drinking and doing everything that their surrogate mum does. Thanks for any info. How to determine their sex would be great too. I live in a suburb which prohibits roosters.
