It's hard to identify causes of variability in egg production when they free range and go broody; there are lots of possible causes, not least hidden nests, so it may appear that they are laying fewer than they actually are.It sounds like my chickens should be able to get enough breakfast from foraging in the summer as our property is big with some forest and grassy areas.
But in the summer they still ate a good amount of feed, which was available all the time, even though they were foraging a lot rotating areas. I know they prefer whatever they can find from foraging over feed. So I thought they just couldn't find enough to fill them up.
Have you noticed any difference in egg production when you fed them in the morning and when you didn't?
What time do you feed them in the afternoon or evening in summer?
Another worry is that they might expose themselves to danger more to forage when they're hungry than they're not.
I'll have to find out from experimenting though.
I feed at dawn and an hour before sunset, whatever the day length.
The roos' job is to lookout for trouble and warn them if danger threatens, and mine do that job better every year. The ones that expose themselves are the independent types, who wander off on their own, or juvenile cockerels, who are sometimes reckless.
That's a good idea to see life as an experiment; be prepared for some losses and enjoy the wins. Good luck!
