Personally, I don't put much credibility in squatting as a sign of imminent laying. Some birds squat, some don't - especially aloof and skittish birds. The trait is a desire to breed, not necessarily that eggs will be forthcoming any time soon. Hens in the presence of a rooster don't squat.Wow. This is a lot of info. Thank you so much for your replies.

None of them are squatting. When they see me they just come running for treats. I do feed them all my kitchen scraps so probably over doing it on the treats. Normally just one large paper plate full daily for them all to share.
