I just purchased 4 sexlinks. All are the same size, with hardly any comb. Two of them still kinda chirp (like my 3 mos old wyandottes) The others sound more like hens. Seller 'forgot' how old they were. Guessed about 16-17 weeks or so. Told me they should be laying soon... (within a week) Then someone tells me they won't lay till about week 22-24 or so..? Can anyone clear this up for me? Hopeing to get a better idea on their age and when I might expect them to begin laying. Thank you!
