I have five pullets: 2 red sexlinks, 2 black sexlinks, and 1 cochin. I get, most days, 4 eggs a day. I'm not sure the cochin is laying yet but I think she is getting close.
One of my black sexlinks lays super jumbo eggs. She doesn't lay everyday, but I would estimate 5 out of 7 days. Oftentimes the chicks take Sunday's off. Now, I would like to think it was for religious purposes but it is really because the dogs are out running around on Saturday and by Sunday I think they are stressed. During the week they are in the house or dog pen so this doesn't happen.
Somedays, I only find 3 eggs. Somedays, one decides not to use the next box and instead uses the area under the roost (ickkkk) and it breaks.
Mine are 4 mos. old at this point.
