I have two 1 year old Black Sexlinks and two 5 month old pullets. I started letting the youngsters free range with the older ladies once they got bigger and I have been putting them in the coop at night with the older ladies. I separate them by putting the younger ones in a cat carrier so the big girls don't pick on the little ones to much as they are still getting to know each other and so they can get used to all of them being in the coop together at night. During the day they spit off into two little groups and the big ones often chase the small ones around the yard, but the small ones are faster so they can get away. The problem is that since I have put them together in the coop at night it seems that my best egg laying Sexlink has stopped laying. I have looked around the yard and can not find any eggs. The other hen is still laying in the nest box. I have found two soft shelled eggs with no yolk in them, so I figured maybe she needed more calcium. I added more oyster shell to her food. Still nothing, it has be a little over 2 weeks now and only the one lays eggs the others are still to young. She seems fine, and her vent is clear. She has also seemed to start sleeping in the nest box at night rather than on the roost lake usual... She does seem to have a small scab on her foot I think might be bumble foot which we are going to tackle tonight. Could that have anything to do with it. It is not big or swollen at all. Any help or opinions would be appreciated!
