Fifer,mine were all weaned by 15th March so are just over 6 weeks old now.They are just starting to flip around the garden and starting their body moult,the sooner they are flying the better,I'm a bag of nerves watching out for cats and bops.
The hens have had 2x10mls,1x15mls the cocks 1x10mls,1x15mls. If it clears later, cocks will go again 10mls.I never train further than 15mls,we have our first race wed,approx 50mls. weather permitting.
