I know this is gonna sound weird but it happened to the MOST UNLIKELY ONES. so I sold my adult flock EXCEPT a Peal white Leghorn and a True Blue (whiting) i have a 10 mixed chciks...aracyanas, rhode island blues, welsummers, etc... They are about 10 weeks... The past 3 weeks they have been sharing a fence with the other girls.... They look at each other but no attcking.... Well about a week about my hens were making and odd clucking sound I havent heard in 20 years..ans i was thinking..."it cant be" well... The white leghorn hasnt left her nesting box in 3 days.... And the true blue is still laying but makes that noise... So maybe she'll be next ....Im looking all over CL for hatching eggs but people want 30 a dozen for mxed mutts.. For that price i could buy day olds and slip em under but i wantnher to have the whole experience... Im asking even ppl whomare selling eggs if theyre hens are with roosters(get my drift).... So weird maybe seeing the chicks did something??!!!! Im from connecticut....
