My 26 week GL Wyandotte is just not herself. After laying 8 eggs in 9 days, no eggs for four. She been moving slow, eating little, drinking ok; she's been in and out of the nest box several times to no avail. Her breathing is a little bit labored. I'm treating her as if she's eggbound- though there have been partial eggs pooed out and shelless. Her butt's been runny and yellowish. I've been setting her in nice warm baths for 1/2 hour periods. She loves it and snoozes! I greased her hinie and put my finger in as far as it would go- just felt a few small (1"?) "balls" that I assume were eggs in the making. I put out oyester shell in case she's low on calcium, though I am feeding her layer with added calcium. Anything else I can do?
