Since first posting, I have locked them up in the coop both Today and Yesterday, and collected eggs in the evening. Both days I've had 3 eggs. Now I'm really puzzled. My husband is a scientist and he says tomorrow we let them out and see what changes- but he is suspicious of the recent changes in humidity and heavy rains somehow affecting their laying. I don't know... maybe. Skunks are abundant around here, so I'm curious if that's what it is. My West Highland Terrier has spent most of the past two nights hunting out in the yard so I know creatures are afoot- likely she's after the rats and voles, but could be something else too.
I'm nervous because I have chicks in the garage that I am waiting to move out into the coop. I don't want to put them out there and have something gobble them up.
I am curious enough that a game cam sounds appealing- but they look expensive so I just don't know if it is worth a few lost eggs. If I let the chickens out and see another decline and stop getting eggs in the evening I may just crack and have to get one.
I will try letting the girls out tomorrow and leaving the coop open, and we'll see what happens. The forecast is bright and sunny- so if it really was a change in weather affecting their laying over the past several weeks and I'm being paranoid, maybe we'll find out. My husband will laugh.
